Question

Mary is twice older than her sister in 5 years time she will be two years older than her sister find how how old are they both

Answer 1

HEYA!!
----------

Let sisters age be X

Mary's age = 2X

After 5 years.

( X+ 5 ).+ 2 = ( 2X +5)

X +5 +2=2X +5

X+7-2X-5=0

-X +2 =0

-X =-2

X=2

Hence sisters age is 2 years

Mary's age is = 4 years .
