Answer 1

Hope it helps

Following is your answer..

Answer 2

Define x:

Let Parthiv be x years old

Krish = x - 5 years old

Find their age 8 years ago:

Parhiv = x - 8

Krish = x - 5 - 8 = x - 13

Solve x:

3 times krish age was 10 more than twice Parthiv's age.

3(x - 13) = 2(x - 8) + 10

3x - 39 = 2x - 16 + 10

3x - 39 = 2x - 6

x = 33

Find their present age:

Parthiv = x = 33

Krish = x - 5 = 33 - 5 = 28 years old

Answer: Krish is 28 years old.
