Q:
A) 91 years | B) 115 years |
C) 103 years | D) Can't be determined |
Answer: C) 103 years
Explanation:
Explanation:
Let present Anirudh's age be 'A' and Bhavana's age be 'B'
Given seven years, their ratio is 7:9
=> A-7 : B-7 = 7 : 9
=> 9A - 7B = 14 .......(1)
And given,
Chandhu is 12 years older than A nad 12 years younger than B
=> C = A + 12....(2)
=> B = C + 12
=> B = A + 12 + 12 .....(From (2))
=> B = A + 24 ....(3)
Put (3) in (1)
9A - 7(A+24) = 14
9A - 7A - 168 = 14
2A = 182
=> A = 91 years
=> C = A + 12 = 91 +12 = 103 years.
