Age of Krishna's daughter is x years

According to the question,

Sum of Krishna and his daughter is 100

To find:

The age of Krishna's daughter.

So,

3x + x = 100

4x = 100

x = 100/4

[By transporting 4 to RHS]

x = 25

So,

The age of Krishna's daughter is x years = 25 years and

The age of Krishna is 3x years = 3 × 25 = 75 years
