Mr. Smith is 81 years older than his grandson, Victor. In 3 years, Mr. Smith will be four times as old as Victor. How old is Victor now?

A) 21 years old

B) 22 years old

C) 24 years old

D) 27 years old

Respuesta :

I’m sure it’s 26 but I can’t find the answer here
Let the age of Victor be x and the age of Mr Smith will be x+81

After 3 years 4(x+3)= x+81+3

4x+12= x +84

4x-x= 84–12= 72

3x = 72. Or x = 24

Now Victor's age is 24 and Mr. Smith is 105

In three years Victor will be 27and Mr. Smith will be 108 (four times of 27)
