Answer : c

Explanation :
Asha=25 Nisha =n Usha =3n

Asha=2a Nisha =a Usha =34
The difference of all ages must be same
=> 25-2a=n-a=3n-34

We will get two equation

=> 2n+a=34

=> n+a=25

From the equation we will get n=9 and a=16

The ages are Asha=2a=32 Nisha =16 and Usha =34

Sum of the ages =100

=> (32+x)+(16+x)+(34+x)=100

=> 82+3x=100

=> 3x=18

=> x=6

=> Age of Usha =34+6=40

Hence (c) is the correct answer.
