Answer 1

ARJUN IS TWICE AS OLD AS SREYA.
FIVE YEARS AGO, HIS AGE WAS THREE TIMES SREYA'S AGE.
FIND THEIR PRESENT AGE.
a = 2s
(a - 5) = 3(s - 5)
s = 10
Arjun is now 20 years old and Sreya 10 years old.

Answer 2

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
