The ages of two friends sunaina and tanish are differ by 2 years sunaina's father is twice as old as sunaina and tanisha is twice as old as his brother shiva the ages of sunaina's father and shiva differ by 40 years

Let S represent Sunaina's age.

Let T represent Tanish's age.

So 2S - T/2 = 40, 4S - T = 80.

Either S - T = 2 or T - S = 2. Let's try both cases.

Either 3S = 78 or 3S = 82.

Since 82 is not a multiple of 3, S = 26.

So Sunaina is 26 years old and Tanish is 24 years old.
