The sum of the present ages of A, B and C is 131 years. 17 years ago from now, the ratio of their ages was 6 : 10 : 4. What is the present age of C (in years)?
A, B और C की वर्तमान आयु का योग 131 वर्ष है। अब से 17 वर्ष पहले, उनकी आयु का अनुपात 6 : 10 : 4 था। C की वर्तमान आयु (वर्षों में) ज्ञात कीजिए।
Detailed Solution & Logic
Correct Answer:
33
17 years ago ratio = $6 : 10 : 4$
Total parts = $20$
Let one part = $x$
So total 17 years ago = $20x$
Present total = $20x + 51 = 131$
$20x = 80$ → $x = 4$
C’s present age = $4x + 17 = 16 + 17 = 33$
Final Answer:
33
