  7. It is too hard to explain but may be it will help you answer is 240/11
    we have to find the one month
    equivalent principal.
    the sum to be paid in
    the first month will be Rs 10 for the first month
    Rs 9 for the second, and soon

    Thus the one month
    equivalent sum = 10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 55

    the amount (principal
    + interest) will be Rs 11, and the interest to be paid = 11 -ยญ 10 = 1

    now the principle = 55 , interest = 1 month = 1/12 years ( converted equivalent to one month)
    Rate = 100 x 12)/ 55 = 240/11
