- B. 23
- C. 23
- D. 23
Answer: Option D
Explanation:
Let, 8 years back, Zaber age was = 8P years
and Adil age was = 8P/8 = P years
after 8 years later,
present age of Zaber = 8P+8 and Adil = P+8
10 years from now, Zaber will be = 8P+8+10
and Adil will be = P+8+10
As per Question,
8P+8+10 = 2(P+8+10)
8P+18 = 2(P+18)
4P+9 = P+18
3P = 9
P = 3
So, present age of Adil = P+8 = 3+8 = 11 years (Ans)
and Adil age was = 8P/8 = P years
after 8 years later,
present age of Zaber = 8P+8 and Adil = P+8
10 years from now, Zaber will be = 8P+8+10
and Adil will be = P+8+10
As per Question,
8P+8+10 = 2(P+8+10)
8P+18 = 2(P+18)
4P+9 = P+18
3P = 9
P = 3
So, present age of Adil = P+8 = 3+8 = 11 years (Ans)
