Question

The sum of mahi's and her mother age is 50 years. One year ago her mother was trice as old as she . Find their presrnt age

Answer 1

Answer:

let x as daughters age

and y as mothers age

so, x + y = 50

y-1 = 3(x-1)

y - 1 = 3 x - 3

y = 3x- 3 + 1

y = 3 x - 2

y = 3 (50 - y ) -2

y = 150 - 3y -2

4 y = 148

y = 148/4

y = 37 (mothers age)

x + 37 = 50

x = 50 - 37

x = 13 daughter's age
