Answers and Solutions for Problems on Ages For IBPS Clerk:

Solutions:

Let the present ages of daughter and mother be d and m respectively.
7d = m
19(d-4) = m-4
=> 19d – 76 = 7d – 4
=> 12d = 72
=> d = 6 and m = 42
Mother’s age four years from now will be 42 + 4 = 46

We have S/t=8/15, Then we have S+9/t+9=11/18 Solve for t we get 45 And S As 24 Difference is 21.

Let their ages be s,n respectively, we have s/n=5/7,
(S+5)/(n+5)=3/4,
4s+20=3n+15
but we have, s=5n/7
so, 20n/7+20=3n+15
Solving for n we have 35.

Ratio of A:B:C = 8:14:22 = 12:21:33
So, the required ratio of ages of A, B, C and D is 12 : 21 : 33 : 44.

Let the present ages of Radha and Sudha be R and S respectively.
Hence, R:S = 7:9 and (R-5):(S-5)=3:4
So, 9R = 7S and 4R-20 = 3S-15 or 4R = 3S+5
From the first equation, 36R=28S and from the second equation, 36R = 27S+45
Therefore, 28S = 27S+45 or S=45
So, Sudha’s age three years from now will be 48 years old.

Let P/q= 3/4, 4 years from hence means adding 4 to present ages of both p,q .
Also q is 5 years bigger than p after 4 years. so, p+9= q+4.
we already have p/q=3/4 or 3q=4p,
so, q=4/3p ,
p+9=4/3p+4,
p/3=5, so Solving for P we get 15.

Let the age of the father be F and the age of the son be S.
So, F:S = 6:1 or F = 6S
Four years later, their respective ages will be F+4 and S+4.
So, (F+4):(S+4)=4:1
So, (6S+4):(S+4)=4:1
Therefore, 6S+4 = 4S+16 or 2S=12 or S=6
Hence, the current age of the son is 6 years.

Let the present ages of Manini be M and Rinu be R respectively
3 years ago the age of Manini was M-3 and Rinu’s age was R-3
It is given that M-3 = 3(R-3)
Now after 8 years age of Manini = M+8 and Rinu’s age after 6 years will be = R + 6
$\frac{R+6}{M+8} = \frac{3}{7}$
Solving the above equations , R = 18 years
2 years hence Rinu’s age will be 18 + 2 = 20 years

Let’s say ages of A and B are 4x and 3x
8 years from now their ages will be = 4x+8 and 3x+8
Hence, $\frac{4x+8}{3x+8} = \frac{6}{5}$
So x=4 and age of A = 16 and age of B = 12
So when B will be 7 year old, A will be 11 year old

$\frac{b+4}{a+4} = \frac{4}{5}$
