Question

Raman is 10 year older than Ruma 5 year ago Raman was twice as old as Roma what is present age of Roman

Answer 1

Roman present age 25 yrs and rumas age is 15 years

Answer 2

let the age of Roma be x

then Raman's age be x+10

5 years ago Roma's age= x-5

5 years ago Raman's age=x+10-5=x+5

so,

x+5=2(x-5)

x+5=2x-10

x-2x= -10-5

-x= -15

the minus sign will be cut and

x=15

age of roma=15 years

age of Raman = x+10=15+10=25 years
