Question

Sindhu is 40 years old and smita is 20 years old how many years age was sindhi 3 times as old as smita ..solution

Answer 1

Let she was 3times before x years,

So,

40 - x = 3(20 - x)

40 - x = 60 - 3x

3x - x = 60 - 40

2x = 20

$x = \frac{20}{2}$
x = 10


It means that she was 3 times of sindhi's age before 10 years.




I hope this will help you
