Answer 2

Right Questions.

Sum of age rohan & ram be 80 , and Rohan elder 20 years than ram, find present ages ..?

Solution

Given :-

• Sum of rohan & ram age = 80
• sohan elder 20 years than mohan

Find :-

• Present age of both

Explanation

Let,

• Present age of Rohan = x years
• Present age of Ram = y years

Case 1.

==> x + y = 80___________(1)

Case 2.

==> x = y + 20

==> x - y = 20____________(2)

Sum of equ(1) & equ(2)

==> 2x = 80 + 20

==> 2x = 100

==> x = 100/2

==> x = 50

keep in equ(1)

==> 50 + y = 80

==> y = 80 - 50

==> y = 30

Hence

• Present age of rohan (x ) = 50 years
• Present age of Ram ( y) = 30 years
