The annual payment of ₹700 in 5 years at the rate of 10%p.a. simple interest will discharge a debt of what amount?

₹4200

The Best way to find the answer:

10% = \(\frac{1}{10}\) ⇒ *add one in every year.*

Year ⇒ 1st  :  2nd  :  3rd  :  4th  :  5th

            10  :   11   :   12   :  13   :  14  ⇒ 60 (total)

1st year value is installment amount = 10R = 700 (given)

Sum of ratio is total amount = 60R = 700 x 6 = 4200
