Answer 1

Answer:

Age of Suma is 40 and and she of Mary is 15

Step-by-step explanation:

let age of Suma be x

and age ofary be y

by statement

x+10=2(y+10)

x+10=2y+20

x-2y=10. 1

x-10=6(y-10)

x-10=6y-60

x-6y=-50. 2

by subtracting 2 from 1

we get 4y=60

y=15

by substituting y=15 in 1

we get x=40
