Question

The ages of Sam and Tom are in the ratio 9:7 . 10 years ago there ages were in the ratio 7:5 . Find their present ages

Answer 1

Answer:

Age of sam is 55 and age of tom is 45 years

Step-by-step explanation:

let the ages be x

Age of sam=9x

Age of tom=7x

After 10 years,

9x +10/7x+10=7/5

By cross multiplication,

5(9x+10)=7(7x+10)

45x+50=49x+70

-45x+49x=70-50

4x =20

x = 20/4

=5

Age of sam = 9x+10=9×5+10

=55 years

Age of tom =7x+10=7×5+10

45 years

Answer 2

Answer:

Sam 55 Tom 65
