Answer 1

Find the interest earned from the 6th to the end of 7th years:

Number of years = 2

Interest = 568 - 520 = Rs 48

Find the interest per year:

Interest per year = 48 ÷ 2 = Rs 24

Find the interest for the first 5 years:

5 years = 24 x 5 = Rs 120

Find the principal amount:

Principal amount = 520 - 120 = Rs 400

Find the interest rate:

Interest rate = 24/400 x 100 = 6%

Answer: The principal amount is Rs 400. The interest rate is 6%
