Options

A. (a) 51 and 85
B. (b) 52 and 87
C. (c) 40 and 75
D. (d) 45 and 70

Answer

B

Explanation

Suppose the age of Jais =x years
Therefore, his father.s age
= x + 35 years
According to question
(x + 5) + (x + 35 + 5) = 135
`implies2x + 45 = 135`
`implies2x=135-45`
`:.x=(90)/(2)=45`
Age of Jais after 12 years
=x+12
40 + 12 = 52 years
Age of his father after 12 years
40 + 35 + 12 = 87 years
