Question

Tom is twice as old as Arul. In 4 years' time, the sum of their ages will be 32 years. Find Arul's present age.​

Answer 1

Explanation:

x = age of Tom

y = age of Arul

x = 2y

x + 4 + y + 4 = 32

x + y + 8 = 32

x + y = 24

using the identity of the first equation gives us

2y + y = 24

3y = 24

y = 8

x = 2y = 2×8 = 16

Arul is 8 years old right now.

Answer 2

Explanation:

X. 2X. (PRESENT AGES)

X+4. 2X+4. ( FOUR YEAR'S TIME AGES)
