Solving Statements Involving Age

3 years ago, ram was 5 times as old as his sister. He is presently 3 times as old as his sister is now. Find their present ages.

Three years ago age of sister = x

Three years ago ram age = 5x

Present age of sister = x + 3

Present Age of Ram = 5x + 3

5x + 3 = 3(x+3)

5x + 3 = 3x + 9

5x-3x = 9-3

2x = 6

Sister age three years ago = 3years

Ram age three years ago = 5 X 3 years = 15 years

Sisternpresent age =  3+ 3 =6 years

Ram present age = 15+ 3 = 18 years.
