Question

a girl is 27 years younger than his father, in 3 years time, the sum of the ages will be 51. how old are they now? please show all workings

Answer 1

Step-by-step explanation:

Let age of father be x years

and age of girl be (x - 27) years

After 3 years

Age of father = ( x + 3) years

Age of girl = {(x- 27) + 3} years

ATQ

(x + 3) + (x - 27 + 3) = 51

x + 3 + x - 24 = 51

2x - 21 = 51

2x = 51 - 21

2x = 30

x = 30/2

x = 15
