Answer 1

Answer: 36 years old

Step-by-step explanation:

Let the age of Sartaj = X years and the age of Vaani = Y years

So,  (X-1)/(Y-1) = 6/7 ............ (1)

and, (X+4)/(Y+4) = 7/8 ..........(2)

So, we have equations as :

7X-6Y = 1 and 7Y-8X = 4. Solve it, X = 31, Y = 36.

So, age of Vaani = Y = 36 Years old.
