Question

Roma's current age is four more than three times the
current age of her cousin Suman. Suman is 12 years
old. Which expression represents Roma's current
age?​

Answer 1

Answer: let suman's age be x, then her mother's age= 4x

agter 20 years their age will be:suman's=x+20, mother's= 4x+20

after 20 years she will be twice suman's age. so:

4x+20=2(x+20)

=4x+20= 2x+40

=4x-2x=40-20

=2x=20

=x=10

therefore suman is 10 years old
