Question

Shirley is 3 years younger than Sammie. The sum of their ages is 25. How old is Shirley?

Answer 1

Answer:

Shirley=11 years

Sammie =14 years

Answer 2

Answer:

Let Shirley's age be X

=> Sammie's age = X + 3

A.T.Q.

X + (X + 3) = 25

X+X+3 = 25

2X + 3 = 25

2X = 25 - 3

2X = 22

X = 22/2

X = 11

Thus, Shirley's age is 11 yrs.

Hope it helps you.
