Question

Sameer is fifteen years elder than Meet. Five years ago, Sameer was three times as old as Meet. What is Sameer's age?

Answer 1

Step-by-step explanation:

Let sameer age = x yrs

Meet age = y yrs

A. T. S, x=y +15 _1

Before 5 yrs,

Sameer age = x-5

Meet age = y-5

A. T. S, x-5 = 3(y-5)

x-5= 3y-15

x-3y+10 =0 _2

By substitution method,

y+15-3y+10=0

-2y+25=0

y = 25/2

x = 25/2+15 ........
