  1. Q.1

    How many paise make 3/4 of a rupee? (A) 30 paise (B) 75 paise (C) 25 paise (D) 34 paise

    Show answer

    Answer: (B) 75 paise. ₹ 1 = 100 paise; 1/4 of 100 = 25, so 3/4 of 100 = 3 × 25 = 75 paise.

  2. Q.2

    Consider these statements:

    1. Every corner of a rectangle is a right angle.

    2. A triangle can have two right angles.

    3. At 6 o'clock the hands of a clock make a straight angle.

    Which of them are correct?

    1. A 1 and 2 only
    2. B 1 and 3 only
    3. C 2 and 3 only
    4. D 1, 2 and 3
    Show answer

    Correct answer: (B) 1 and 3 only

    All four corners of a rectangle are right angles, and at 6:00 the hands lie in one straight line (180°). In a 'triangle' with two right angles, the two sides standing on the base would be parallel and never meet, so statement 2 is wrong.

  3. Q.3

    A pictograph of trees in four villages uses the key one symbol = 10 trees: P has 4 symbols, Q 6½, R 3 and S 5½. Which statement is NOT correct?

    1. A R has exactly half as many trees as Q.
    2. B Q has 65 trees.
    3. C P and R together have 70 trees.
    4. D S has 15 more trees than P.
    Show answer

    Correct answer: (A) R has exactly half as many trees as Q.

    P = 40, Q = 65, R = 30 and S = 55 trees. Half of 65 is 32½, not 30, so the statement about R and Q is wrong; the others are true (40 + 30 = 70, 55 − 40 = 15).

  4. Q.4

    Since 9 = 10 − 1, nine times a number equals ten times the number minus the number. Using this pattern, 9 × 47 = ?

    1. A 437
    2. B 517
    3. C 423
    4. D 432
    Show answer

    Correct answer: (C) 423

    9 × 47 = 470 − 47 = 423. Check: 9 × 40 + 9 × 7 = 360 + 63 = 423. (517 adds 47 instead of subtracting it.)

  5. Q.5

    A pattern for multiplying a two-digit number by 11: 11 × 23 = 253 (write 2 and 3, and put 2 + 3 = 5 between them). Using this pattern correctly, 11 × 68 = ?

    1. A 748
    2. B 6148
    3. C 648
    4. D 758
    Show answer

    Correct answer: (A) 748

    6 + 8 = 14, so write 4 in the middle and carry 1 to the 6: 6 + 1 = 7, giving 748. Check: 68 × 10 + 68 = 680 + 68 = 748.

  7. Q.7

    A triangle is placed on top of a square so that one side of the triangle exactly matches the top side of the square, like the outline of a hut. How many sides and corners does the outline of the new shape have?

    1. A 7 sides and 7 corners
    2. B 5 sides and 5 corners
    3. C 6 sides and 5 corners
    4. D 7 sides and 5 corners
    Show answer

    Correct answer: (B) 5 sides and 5 corners

    The shared side goes inside and is no longer part of the outline. The outline has 3 sides of the square and 2 sides of the triangle, so 5 sides and 5 corners (2 at the bottom, 2 where the roof meets the walls and 1 at the top).

  8. Q.8

    There are 45 children in a class, and 2/5 of them come to school by bus. How many children do NOT come by bus?

    1. A 43 children
    2. B 27 children
    3. C 18 children
    4. D 9 children
    Show answer

    Correct answer: (B) 27 children

    1/5 of 45 = 9, so 2/5 of 45 = 18 children come by bus. The remaining 45 - 18 = 27 children (3/5 of the class) do not.

    Tally of vehicles passing a school gate: cars - 3 groups of five and 4 marks; buses - 1 group and 2 marks; two-wheelers - 6 groups and 1 mark; autos - 2 groups only. How many vehicles passed in all?

    1. A 55 vehicles
    2. B 67 vehicles
    3. C 57 vehicles
    4. D 19 vehicles
    Show answer

    Correct answer: (B) 67 vehicles

    Cars 15 + 4 = 19, buses 5 + 2 = 7, two-wheelers 30 + 1 = 31, autos 10; total = 19 + 7 + 31 + 10 = 67. (55 comes from counting each group as 4.)

  10. Q.10

    Meena divides 754 by 9 and gets quotient 83 and remainder 7. Which calculation correctly checks her answer?

    1. A 9 × 7 + 83 = 754
    2. B 9 × 83 + 7 = 754
    3. C 9 × 83 + 9 = 754
    4. D (83 + 7) × 9 = 754
    Show answer

    Correct answer: (B) 9 × 83 + 7 = 754

    Dividend = divisor × quotient + remainder: 9 × 83 = 747 and 747 + 7 = 754, so her answer is right. The other calculations give 756, 810 and 146, not 754.

    A poultry farm packs 1,000 eggs in trays of 30. What is the greatest number of trays that can be completely filled, and how many eggs are left over?

    1. A 33 trays, 10 eggs left over
    2. B 34 trays, 10 eggs left over
    3. C 32 trays, 40 eggs left over
    4. D 330 trays, 10 eggs left over
    Show answer

    Correct answer: (A) 33 trays, 10 eggs left over

    30 × 33 = 990, and 1,000 - 990 = 10 eggs are left, too few for another tray. With 32 trays, 40 eggs would be left, enough to fill one more tray.

  12. Q.12

    In a magic triangle, the numbers 1 to 9 are placed on the sides, four on each side, so that every side has the same sum. If 1, 2 and 3 are at the corners, what is the sum of each side?

    1. A 17
    2. B 15
    3. C 18
    4. D 16
    Show answer

    Correct answer: (A) 17

    Adding the three sides counts every number once and each corner twice: 45 + (1 + 2 + 3) = 51. So each side is 51 ÷ 3 = 17; one arrangement is 1, 6, 8, 2 / 2, 5, 7, 3 / 3, 4, 9, 1.

    3. C 273 m
    4. D 17,435 m
    Show answer

    Correct answer: (A) 263 m

    8,849 - 8,586 = 263 m. Check: 8,586 + 263 = 8,849. The answer 343 comes from taking the smaller digit from the larger in each column.

    A truck carries 48 bags of cement of 50 kg each and 26 boxes of tiles of 35 kg each. What is the total load?

    1. A 6,290 kg
    2. B 3,210 kg
    3. C 3,310 kg
    4. D 3,410 kg
    Show answer

    Correct answer: (C) 3,310 kg

    Cement: 48 × 50 = 2,400 kg; tiles: 26 × 35 = 910 kg. Total = 2,400 + 910 = 3,310 kg. (6,290 kg wrongly multiplies all 74 items by 85 kg.)

    Data to be shown in a bar graph: 120, 340, 260 and 180. The graph paper is 20 squares tall. Which scale makes every bar end exactly on a grid line and still lets the longest bar fit?

    1. A 1 square = 10 units
    2. B 1 square = 20 units
    3. C 1 square = 40 units
    4. D 1 square = 50 units
    Show answer

    Correct answer: (B) 1 square = 20 units

    With 1 square = 20 the bars are 6, 17, 13 and 9 squares, all whole and within 20. With 10 the longest bar needs 34 squares; with 40 or 50 some bars end between grid lines (340 ÷ 40 = 8.5, 120 ÷ 50 = 2.4).

    A rectangle is 8 cm long and 5 cm wide. What is its perimeter?

    1. A 13 cm
    2. B 21 cm
    3. C 26 cm
    4. D 40 cm
    Show answer

    Correct answer: (C) 26 cm

    Perimeter = 8 + 5 + 8 + 5 = 2 × (8 + 5) = 26 cm. 13 cm counts only two sides, and 40 is the area in square cm.

    In a class survey of favourite fruits, the tally for mango shows 6 complete groups of five and 2 more marks. How many children chose mango?

    1. A 26 children
    2. B 62 children
    3. C 8 children
    4. D 32 children
    Show answer

    Correct answer: (D) 32 children

    Each complete group stands for 5, so 6 groups = 30, and 2 more marks make 30 + 2 = 32 children. (26 comes from wrongly counting a group as 4.)

    2. B 15/35
    3. C 33/35
    4. D 18/35
    Show answer

    Correct answer: (A) 21/35

    35 = 5 × 7, so multiply both numerator and denominator by 7: 3/5 = (3 × 7)/(5 × 7) = 21/35. Writing 33/35 adds 30 to the numerator instead of multiplying.

    A rectangle 3 cm × 2 cm is cut off from one corner of a rectangle 8 cm × 6 cm, along the sides of the big rectangle. What is the perimeter of the remaining shape?

    1. A 18 cm
    2. B 23 cm
    3. C 28 cm
    4. D 33 cm
    Show answer

    Correct answer: (C) 28 cm

    The original perimeter is 2 × (8 + 6) = 28 cm. Cutting the corner removes 3 cm and 2 cm of boundary but adds two new edges of 3 cm and 2 cm, so the perimeter stays 28 cm (though the area falls from 48 to 42 sq cm).

    In tally marks every fifth mark is drawn across four marks to make a group of five. 23 = 4 × 5 + 3, so it is 4 groups of five and 3 single marks; single marks are never left at 5 or more.

    Without adding, decide which of the following sums is odd.

    1. A 11 + 15 + 21 + 33
    2. B 46 + 52 + 64
    3. C 17 + 23 + 35
    4. D 19 + 27 + 34
    Show answer

    Correct answer: (C) 17 + 23 + 35

    A sum is odd only when it has an odd count of odd numbers: 17 + 23 + 35 has three odd numbers, so it is odd (75). The others have two, four or no odd numbers: 80, 80 and 162 are even.

    Which of the following is NOT equal to 47 mm?

    1. A 4.7 cm
    2. B 4 cm 7 mm
    3. C 47/10 cm
    4. D 0.47 m
    Show answer

    Correct answer: (D) 0.47 m

    Since 10 mm = 1 cm, 47 mm = 4 cm 7 mm = 4.7 cm = 47/10 cm. But 0.47 m = 47 cm = 470 mm, ten times as long.

    Four packets of the same rice are on sale: 400 g for ₹ 52, 1 kg for ₹ 125, 250 g for ₹ 35 and 500 g for ₹ 60. Which packet gives rice at the cheapest rate (the lowest price for the same weight)?

    1. A 400 g for ₹ 52
    2. B 500 g for ₹ 60
    3. C 1 kg for ₹ 125
    4. D 250 g for ₹ 35
    Show answer

    Correct answer: (B) 500 g for ₹ 60

    Cost of 100 g: 52 ÷ 4 = ₹ 13, 125 ÷ 10 = ₹ 12.50, (35 × 2) ÷ 5 = ₹ 14 and 60 ÷ 5 = ₹ 12. The 500 g packet is cheapest at ₹ 12 per 100 g.

    Which of these arrangements of six equal squares, joined edge to edge, can be folded into a cube?

    1. A A row of 4 squares, with one square above the 2nd and one below the 3rd
    2. B A row of 4 squares, with one square above the 1st and one above the 2nd
    3. C A single row of 6 squares
    4. D Two rows of 3 squares each, forming a rectangle
    Show answer

    Correct answer: (A) A row of 4 squares, with one square above the 2nd and one below the 3rd

    A row of 4 folds into the four side faces of the cube; a square above any of them becomes the top and a square below any of them becomes the bottom. With both extra squares above the row, two faces overlap on top and the bottom stays open; a row of 6 or a 2 × 3 rectangle also leaves faces overlapping or open.

    How many faces, edges and corners does a cube have?

    1. A 6 faces, 8 edges, 12 corners
    2. B 6 faces, 12 edges, 8 corners
    3. C 8 faces, 12 edges, 6 corners
    4. D 4 faces, 12 edges, 8 corners
    Show answer

    Correct answer: (B) 6 faces, 12 edges, 8 corners

    A cube (like a die) has 6 square faces, 12 edges where two faces meet, and 8 corners where three edges meet. Swapping the numbers of edges and corners is a common slip.

    2. B 2,820
    3. C 1,410
    4. D 141
    Show answer

    Correct answer: (C) 1,410

    The 3 in 36 stands for 3 tens, so the second partial product is 47 × 30 = 1,410. Then 282 + 1,410 = 1,692 is the final product.

    A shop opens at 9:30 a.m. and closes at 8:15 p.m. It is shut for 1 hour 15 minutes for lunch. For how long is it open in a day?

    1. A 9 hours 30 minutes
    2. B 10 hours 45 minutes
    3. C 12 hours
    4. D 9 hours 45 minutes

    Correct answer: (A) 9 hours 30 minutes

    From 9:30 a.m. to 8:15 p.m. (20:15) is 10 hours 45 minutes. Taking away the lunch break leaves 10 h 45 min − 1 h 15 min = 9 hours 30 minutes.

    Tea is made for 36 guests at a school function. Each cup needs 150 mL of milk, and milk is sold only in 500 mL packets costing ₹ 28 each. What is the least amount that must be spent on milk?

    1. A ₹ 280
    2. B ₹ 302.40
    3. C ₹ 308
    4. D ₹ 151.20
    Show answer

    Correct answer: (C) ₹ 308

    Milk needed = 36 × 150 = 5,400 mL. 10 packets give only 5,000 mL, so 11 packets are needed. Cost = 11 × 28 = ₹ 308. (₹ 280 buys 10 packets, which is not enough.)
