1. The HCF of 90, 150 and 210 is

  1. A
    6
  2. B
    10
  3. C
    15
  4. D
    30
Show answer

Answer: D. 90 = 2 × 32 × 5, 150 = 2 × 3 × 52, 210 = 2 × 3 × 5 × 7. All three primes 2, 3 and 5 are common, so the HCF is 2 × 3 × 5 = 30. 6, 10 and 15 each leave out one common prime.

2. A table is sold at a loss of 8%. Had it been sold for Rs 300 more, there would have been a gain of 4%. What is the cost price?

  1. A
    Rs 2,400
  2. B
    Rs 2,500
  3. C
    Rs 3,750
  4. D
    Rs 7,500
Show answer

Answer: B. The extra Rs 300 moves the result from −8% to +4%, i.e. 12% of cost. So cost = 300 ÷ 0.12 = Rs 2,500. Rs 3,750 uses only 8%.

3. One root of x2 − kx + 18 = 0 is 3. The value of k is

  1. A
    6
  2. B
    9
  3. C
    15
  4. D
    27
Show answer

Answer: B. The roots multiply to 18, so the other root is 6, and k = sum of roots = 3 + 6 = 9. 6 is the other root, not k.

4. A bus travels for 2 hours at 50 km/h and then for 3 hours at 70 km/h. Its average speed for the whole journey is

  1. A
    60 km/h
  2. B
    62 km/h
  3. C
    64 km/h
  4. D
    66 km/h
Show answer

Answer: B. Total distance = 100 + 210 = 310 km in 5 h, so the average is 310 ÷ 5 = 62 km/h. Averaging the two speeds gives 60.

5. The distance between (2, 3) and (5, k) is 5 units, and k is greater than 3. What is k?

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

Answer: D. 3² + (k − 3)² = 25 gives (k − 3)² = 16, so k − 3 = ±4. With k > 3, k = 7 (the other value, −1, is ruled out).

6. The average salary of 8 office staff is Rs 30,000. When a manager joins, the average rises to Rs 32,000. What is the manager's salary?

  1. A
    Rs 34,000
  2. B
    Rs 40,000
  3. C
    Rs 46,000
  4. D
    Rs 48,000
Show answer

Answer: D. New total = 9 × 32,000 = Rs 288,000 and the old total = 8 × 30,000 = Rs 240,000, so the manager earns Rs 48,000.

7. At a shop, 120 of the last 500 customers paid by card. Using this as the probability, how many of tomorrow's 800 customers would you expect to pay by card?

  1. A
    96
  2. B
    120
  3. C
    160
  4. D
    192
Show answer

Answer: D. Estimated probability = 120/500 = 0.24, so expected card payments = 0.24 × 800 = 192.

8. The smallest positive number that leaves a remainder of 3 when divided by 4, by 6 and by 9, and is also divisible by 7, is

  1. A
    39
  2. B
    75
  3. C
    111
  4. D
    147
Show answer

Answer: D. The number is 36k + 3, since LCM(4, 6, 9) = 36. Trying k = 1, 2, 3, 4 gives 39, 75, 111, 147, and 147 = 7 × 21 is the first multiple of 7.

9. Two jugs of equal size are full of milk and water: in the first, milk : water = 3 : 1 and in the second, milk : water = 1 : 1. Both jugs are poured into one large container. What is the ratio of milk to water in the mixture?

  1. A
    5 : 3
  2. B
    2 : 1
  3. C
    3 : 1
  4. D
    7 : 5
Show answer

Answer: A. Take each jug as 1 unit: milk = 3/4 + 1/2 = 5/4 and water = 1/4 + 1/2 = 3/4, so the ratio is 5 : 3. 2 : 1 comes from adding the ratio terms (4 : 2), which is wrong because the jugs have different numbers of parts.

10. If f(x) = 5x − 7, what is the value of f−1(8)?

  1. A
    0.2
  2. B
    1.6
  3. C
    3
  4. D
    33
Show answer

Answer: C. f−1(8) is the x with 5x − 7 = 8, so 5x = 15 and x = 3. The value 33 is f(8), not the inverse.

11. A mother is 4 times as old as her daughter. In 10 years she will be 2.5 times as old as her daughter. The daughter's present age is

  1. A
    10 years
  2. B
    15 years
  3. C
    20 years
  4. D
    40 years
Show answer

Answer: A. 4d + 10 = 2.5(d + 10) gives 1.5d = 15, so d = 10 (mother 40; in 10 years 50 and 20, ratio 2.5). 40 is the mother's age.

12. Taking π = 22/7, what is the circumference of a circle of radius 7 cm?

  1. A
    44 cm
  2. B
    88 cm
  3. C
    154 cm
  4. D
    308 cm
Show answer

Answer: A. C = 2πr = 2 × 22/7 × 7 = 44 cm. Using the diameter in 2πr gives 88 cm, and 154 is the area in cm².
