Question

Arun is twice as old as Amal now and the sum of their ages 5 years hence will be 100. What is the present age of Arun.​

Answer 1

Step-by-step explanation:

Arun=x

amal=y

arun=amal×2

x=2y

After 5 years

x+5+y+5=100

x+y=90

but x is 2y

so

y+2y=90

3y=90

y=30

and

x=60

(Not sure if this is the correct answer as i can't understand on what you are trying to convey)
