Answer 2

Explanation:

The question asks about interest "...at the end of 3/7 year...if it was compounded yearly" but 3/7 year is less than one year.

Applying the general equation for compound interest:

total debt at the end = principal * (1 + interest rate)^(number of years)

= 40000 * (1 + 10%)^(3/7)

= 40000 * 1.1^(3/7)

= 41667.72

Subtracting the principal, the interest paid:

= 41677.72 - 40000

= 1677.72 rupees
