(Show all workings) 1/4 of morolake’s age nine years ago is the same as 1/5 of her age next year. What is morolake age now

Answer 1

Let Morolake's age now be x

1/4 of Morolake's age nine years ago = (x-9)/4

1/5 of her age next year = (x+1)/5

Equating the two:

(x-9)/4 = (x+1)/5

5(x-9) = 4(x+1)

5x - 45 = 4x + 4

x = 49

Morolake's age now is 49.
