  • Let SI be Total Interest at the end of 4 months for the Principal amount of ₹ 7700
    SI can be calculated as follows
    4408 = (7700 * R * 4)/100 (as the interest per month is R and the number of months is 4)
    R = (4408 * 100) / (7700 * 4)
    Therefore Rate of interest R = 14.311688311688% per month
    Therefore Rate of interest R = 14% per month (round off to nearest value)
