Ram is 55 years old and Sam is 25 years old. How many years ago was Ram three times as old as Sam?

Present age of Ram = 55 years

Present age of Sam = 25 years

Let x be the number of years ago when Ram was three times as old as Sam.

At that time:

Ram's age would have been 55 - x years.

Sam's age would have been 25 - x years.

According to the question:

​$$55 - x = 3 \times (25 - x)$$​​

55 - x = 75 - 3x

3x - x = 75 – 55

2x = 20

x = $$\frac{20}{2}$$​= 10

x = 10

Thus, 10 years ago, Ram was three times as old as Sam.
