Problem on Ages
The average age of Ram and his two children is 17 years and the average age of Ram`s wife and the same children is 16 years. If the age of Ram is 33 years, the age of his wife is (in years):

a) 31
b) 32
c) 35
d) 30



Answer
Solution
Correct Answer Is : 30
Solution Is : Ram + two children =51 years
His wife + two children =48 years
Therefore, Ram -Wife =3 years
⇒ 33- wife =3 years
Therefore wife =33-3 = 30 years
Eighteen years ago, the ratio of A`s age to B`s age was 8 : 13. Their present ratios are 5 : 7. What is the present age of A ?

a) 70 years
b) 50 years
c) 40 years
d) 60 years



Answer
Solution
Correct Answer Is : 50 years
Solution Is : Let the A`s age and B`s age was 8x and 13x
According to question, (8x+18)/(13x+18) = 5/7
=> 56x+18*7 = 65x+18 *5
=> 65x-56x =18*7 - 18*5
=> 9x=18*2
x=4
Hence, the present age of A
=> 8*4+18 =50years.
The sum of the ages of two brothers, having a difference of 8 years between them, will double after 10 years. What is the ratio of the age of the younger brother to that of the elder brother ?

a) 10:13
b) 7 : 11
c) 3:07
d) 8:09



Answer
Solution
Correct Answer Is : 3:07
Solution Is : Age of younger brother =x years. Age of elder brother =(x+8) years.
Therefore after 10 years,
x+x+8+20=2(x+x+8)
2x+28=4x+16
4x-2x=28-16
2x=12 ⇒x=12/2 =6
Therefore required ratio
=6:(6+8) = 6:14 =3:7
X is four years older than Y who is twice as old as Z. If the total age of X, Y and Z be 34, how old is X?

a) 8
b) 10
c) 12
d) 16



Answer
Solution
Correct Answer Is : 16
Solution Is : Let Z`s age be x years. Then, Y`s age
= 2x years. X`s age = (2x + 4) y
ears. (2x + 4) + 2x + x = 34
5x = 30
x = 6
Hence, X`s age = 2x + 4 = 2 x 6 + 4 = 16 years.
A man had 7 children. When their average age was 12 years, a child aged 6 died. The average age of remaing 6 children is

a) 13 years
b) 10 years
c) 11 years
d) 14 years



Answer
Solution
Correct Answer Is : 13 years
Solution Is : Average age of 7 children = 12 years.
Therefore, Excess of average age than the age of child died
= 12 - 6. = 6 years.
Therefore, Increase in ages of the remaining 6 children = 6/6 = 1 years
Therefore, ages of remaining 6 children = 12 + 1 = 13 years.

a) 24
b) 4
c) 40
d) 14



Answer
Solution
Correct Answer Is : 4
Solution Is : (2) Suppose the age of son is x years
Therefore, age of father=10x years
According to the question,
(10x+x)/2=22
⇒11x=44
∴x=44/11=4 years
Age of father = 10×4=40 years.
