Let us assume, x and y are the present ages of Arjun and Shreya.
Given:
x = 2y ---------------1
also given, 5 years ago
x - 5 = 3 (y - 5)
x - 5 = 3y - 15
3y - x = 10 ---------------------2
Substitute the value of x from equation 1 in equation 2
3y - 2y = 10
y = 10 years
Therefore, x = 2y = 2*10 = 20 years
Answer - The present age of Arjun is 20 years and present age of Shreya is 10 years
