At Present

_________,

Let Shriya age = x years

Arjun age = 2x years

5 years ago ,

__________

Shriya age = ( x - 5 ) years 

Arjun age = ( 2x - 5 ) years 

according to the problem given ,

2x - 5 = 3 ( x - 5 )

2x - 5 = 3x - 15

10 = x

Therefore ,

At present ,

Shriya age = x = 10 years 

Arjun age = 2x = 2 × 10 = 20 years
