Ten Quantitative · Arithmetic questions with answers

Try each one, then open the answer. These ten stay the same; the test draws new ones every time.

1. The price of a phone including 17% sales tax is Rs 4,680. The price before tax was

  1. A
    Rs 3,884
  2. B
    Rs 4,100
  3. C
    Rs 4,000
  4. D
    Rs 3,900
Show answer

Answer: C. Rs 4,680 is 117% of the pre-tax price, so the price is 4680 ÷ 1.17 = Rs 4,000. Taking 17% off Rs 4,680 (about Rs 3,884) is wrong because the tax was 17% of the smaller pre-tax price.

2. Zara drives from Lahore to Faisalabad at 60 km/h and returns by the same road at 40 km/h. Her average speed for the whole journey is

  1. A
    48 km/h
  2. B
    50 km/h
  3. C
    45 km/h
  4. D
    52 km/h
Show answer

Answer: A. For equal distances the average speed is 2 × 60 × 40/(60 + 40) = 48 km/h. The simple mean 50 km/h is wrong because more time is spent at the slower speed.

3. Sana can complete a task in 15 days. She works for 5 days and then leaves, and Fatima finishes the remaining work in 20 days. Fatima alone could do the whole task in

  1. A
    25 days
  2. B
    20 days
  3. C
    40 days
  4. D
    30 days
Show answer

Answer: D. Sana does 5/15 = 1/3 of the task, leaving 2/3. Fatima does 2/3 in 20 days, so the whole task takes her 20 × 3/2 = 30 days.

4. 35% of 240 is

  1. A
    84
  2. B
    72
  3. C
    96
  4. D
    48
Show answer

Answer: A. 10% of 240 is 24, so 35% = 3.5 × 24 = 84. 72 is 30% and 96 is 40%.

5. In an examination 60% of the candidates passed and 480 failed. The number of candidates was

  1. A
    800
  2. B
    1,200
  3. C
    720
  4. D
    1,600
Show answer

Answer: B. The 480 who failed are 40% of the candidates, so the total is 480 ÷ 0.4 = 1,200. Dividing by 0.6 gives 800, which treats the failures as the 60%.

6. A motorcycle costs Rs 90,000 in cash. On instalments it is sold for a down payment of Rs 30,000 and 12 monthly instalments of Rs 5,500. How much more does the instalment buyer pay than the cash price?

  1. A
    Rs 3,000
  2. B
    Rs 6,000
  3. C
    Rs 36,000
  4. D
    Rs 66,000
Show answer

Answer: B. Instalment total = 30,000 + 12 × 5,500 = 30,000 + 66,000 = Rs 96,000, which is Rs 6,000 more than the cash price. Rs 66,000 is the instalments alone, without the down payment.

7. A and B together can finish a job in 6 days. A alone can finish it in 10 days. B alone would take

  1. A
    16 days
  2. B
    15 days
  3. C
    4 days
  4. D
    12 days
Show answer

Answer: B. B's daily work = 1/6 − 1/10 = (5 − 3)/30 = 1/15, so B alone takes 15 days. Subtracting the days (10 − 6 = 4) is the common slip.

8. The value of 2/3 + 3/4 − 5/6 is

  1. A
    5/12
  2. B
    9/4
  3. C
    7/12
  4. D
    1/12
Show answer

Answer: C. With denominator 12: 8/12 + 9/12 − 10/12 = 7/12. Adding the 5/6 instead of subtracting gives 27/12 = 9/4.

9. A boat has a speed of 10 km/h in still water and the stream flows at 2 km/h. The time to travel 24 km downstream is

  1. A
    3 h
  2. B
    2 h
  3. C
    2.4 h
  4. D
    1½ h
Show answer

Answer: B. Downstream speed = 10 + 2 = 12 km/h, so time = 24 ÷ 12 = 2 h. Using the upstream speed of 8 km/h gives 3 h.

10. The smallest three-digit number which leaves a remainder of 2 when divided by 6, by 8 and by 10 is

  1. A
    118
  2. B
    120
  3. C
    242
  4. D
    122
Show answer

Answer: D. The number is 2 more than a common multiple of 6, 8 and 10. The least such multiple is LCM = 120, so the number is 122. 120 itself leaves remainder 0, 118 subtracts the 2 instead of adding it, and 242 is the next such number.
