Answer 2

Sam returned the money in 5 years.

Given: Rate of simple interest = 6% per annum

The amount borrowed by Sam = ₹12000

The money paid back by Sam = ₹15600

To Find: After how many years Sam returned the money

Solution:

We know that Simple Interest is given as

SI = P x R x T, where P is the principal amount borrowed, R is the rate of interest per annum and T is the time period in years

Total amount to be returned = SI + Principal amount

Here, the returned amount was ₹15600, and the borrowed amount, i.e., the principal was ₹12000

15600 = SI + 12000

SI = 15600 - 12000

SI = ₹3600

Px R x T = 3600

12000 x $\frac{6}{100}$ x T = 3600

T = $\frac{60}{12}$

T = 5 years

Therefore, Sam returned the money after 5 years.
