The ratio of present age of Abhi and Ronak is 3 : 4. 12 years from now, the ratio of their ages will be 5 : 6. If Nishan is 8 years younger than Ronak, then find ratio of age of Nishan and Ronak 4 years hence?
Answer & explanation
Correct answer: option 2
A : R
3 : 4
↓+2R = 12 years ⇒ 1R = 6 years
5 : 6
Hence,
Ronak present age = 4 × 6 = 24 years
Nishan is 8 years younger to Ronak, so Nishan age = 24 - 8 = 16 yeras
Ronak's age 4 years hence = 24 + 4 = 28 years
Nishan's age 4 years hence = 16 + 4 = 20 years
Required ratio, R : N = 28 : 20 = 7 : 5
