Raju is 42 years younger than Kamal. Raju's age is 35% of the sum of his and Kamal's age. What will be Kamal's age after 3 years ?
Answer & explanation
Correct answer: option 3
35%= \(\frac{7}{20}\)
Raju : Kamal : Sum : Difference
7 : 13 : 20 : 6
↓ x7
42 (given)
⇒ 1R = 7
Kamal's age at present = 13 × 7 = 91 years
Kamal's age after 3 years = 91 + 3 = 94 years
