42Railway RRB : Model paper 1
Total age of 6 members now
= (24 × 6) = 144 years
Sum of the ages of 2 children
= (144 - 136) = 8 years
Let the age of the younger child be x years.
Then, age of the elder child = (x + 2) years
So,
x + x + 2 = 8
2x = 6
x = 3
So, age of younger child = 3 years
33.Option C
31 × 31 - 30 × 30 = 61 years
34. Option C
Let the present ages of the man and his wife be 4x and 3x years respectively.
Then,
=
7 (4x + 4) = 9 (3x + 4)
x = 8
So, their present ages are 32 years and 24 years respectively.
Suppose they were married z years ago.
⎯
⎯
Then,
=
3 (32 - z) = 5 (24 - z)
