Each of the 4 daughters get = Rs 2x
Each of the 5 sons get = Rs 6x

So 39x = 390000
X=10000 = wife’s share

A) 12 B) 14
C) 15 D) 19
 
Answer & Explanation Answer: C) 15

Explanation:

                                                               Father           Son

 

5years ago the age of the father & son           5X                X

 

present the age of the father & son              5X+5             X+5

 

(present age of father) + (present age of son) = 70

 

       (5x+5)                 +        (x+5)              = 70

 

 Then you will get X = 10

 

Present age of the son (x+5) = 15
