Answer 2

Given - Principal, amount and rate of interest

Find - Time period

Solution - The time period is 12.5 years.

The formula to be used for calculation is -

Simple interest = Principal*Rate of interest*Time/100

Another formula -

Amount = Principal + Interest

Now, let the principal be x. The amount will be 3x.

Interest = 3x - x

Interest = 2x

Keep the values in the formula to find the time period.

Time = 2x*100/x*16

Time = 200/16

Time = 12.5 years

Thus, the time period is 12.5 years.
