Answer key:

1. (C) 2. (C) 3. (A) 4. (C) 5. (A) 6. (B) 7. (A) 8. (A) 9. (B) 10. (A)

Answers Explanation:

1. Assume that Sunil’s present age = x.
Then father’s present age = 3x + x = 4x
After 8 years, father’s age =212212 times of Sunils’ age
=> (4x+8) = (5/2)(x+8)
=> x = 8
After further 8 years,
Sunil’s age = x + 8 + 8 = 24
Father’s age = 4x + 8 + 8 = 48
Father’s age/Sunil’s age = 48/24 = 2

2. Let the age before 10 years = x
Then 125x/100= x + 10
=>125x = 100x + 1000
=> x = 1000/25 = 40
Present age = x + 10 = 40 +10 = 50

3. Given that If selling price is doubled, the profit triples
⇒2y–x=3(y−x)         ⇒2y–x=3y−3x         ⇒y=2x
⇒Profit%=(Profit/CP)×100
=((y−x)/x)*100       =((2x–x)/x)*100      =(x/x)100=100%

4. Loss in speed when including stoppages = 54 – 45 = 9kmph
=> In 1 hour, bus covers 9 km less due to stoppages
Hence, time that the bus stop per hour = time taken to cover 9 km
=distance/speed       =9/54 hour    =16 hour

5. Largest 4 digit number = 9999
9999 ÷ 88 = 113, remainder = 55
Hence largest 4 digit number exactly divisible by 88 = 9999 – 55 = 9944

6. LCM of numerators = 10
HCF of denominators = 1
=> 10/1 = 10

7. Amount of work P and Q can together do in 4 days = 4 × (7/60) = 7/15
Fraction of work left = 1 – 7/15= 8/15

8. together work in 1 day = 1/4
Amount of work R can do in 1 day = 1/4 – (1/16 + 1/12) = 3/16 – 1/12 = 5/48
=> Hence R can do the job on 48/5 days = 9 (3/5) days

9. 4/12 + x/15 = 1
x = 10

10. 1/x – 1/20 = -1/24
x = 120
120 * 4 = 480
