Answer:
Raj's present age = 16
Step-by-step explanation:
Let raj's sister's present age be 'x'
Raj's present age is 'x+3'
After 5 years :
Raj age = x+3+5 = x+8
Raj's sister's age = x+5
Sum of Raj's & his sister's age after 5 years = 39
(x+8) + (x+5) = 39
2x + 13 = 39
2x = 39 - 13
2x = 26
x = 13
Raj's present age = x + 3 = 13 + 3 = 16
