Step-by-step explanation and Answer
Since the interest rate is 5%, and the first loan was borrowed on May 1, we can calculate the interest on the first loan by using the formula:
Interest = Principal x Rate x Time
In this case, the principal is 2000, the rate is 5% (expressed as a decimal), and the time is (September 24 - May 1) = 4.5 months
So, Interest = 2000 x 0.05 x 4.5/12 = 50
The same applies to the second loan of 1000, so the interest on this loan is:
Interest = 1000 x 0.05 x (4.5/12) = 25
To find the total amount returned, we add the interest on both loans to the total principal borrowed:
total = 2000 + 1000 + 50 + 25 = 3075
Therefore, the total amount returned is Ks 3075
