Sonu is 24 years younger than Sushil. Sonu's age is 30% of the sum of his and Sushil's age. What will be sushil's age after 7 years ?
Answer & explanation
Correct answer: option 4
30%= \(\frac{3}{10}\)
Sonu : Sushil : Sum : Difference
3 : 7 : 10 : 4
↓ x6
24 (given)
⇒ 1R = 6
Sushil's age at present = 6 × 7 = 42 years
Sushil's age after 9 years = 42 + 7 = 49 years
