Correct Answer: 3
Explanation:
According to the given data,
P + Q = 41 ......(1)
R - 1 = P + 2
R = P + 3
and
P + 4 = Q - 1
=> Q = P + 5 ....(2)
From (1)&(2)
P = 18
Q = 18 + 5 = 23
R = 18 + 3 = 21
=> P/S = 3/4
=> S = 4/3 x 18 = 24
Required Difference = S - R = 24 - 21 = 3.
Correct Answer: 103 years
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.
Correct Answer: 40 yrs

Let the mother's present age be x years.
Then, the person's present age = 2/5 x years.

2(2x + 40) = 5(x + 8) => x = 40.
