Answer:
1512
Step-by-step explanation:
Given A man borrows money from a finance company and has to pay it back in two equal half-yearly installments of Rs. 7,396 each. If the interest is charged by the finance company at the rate of 15% per annum, compounded semi-annually, find the principal and the total interest paid.
Now we know amount paid in two installments will be 2 x 7396 = Rs 14792
Rate for half yearly will be 15/2%
So Principal for first installment will be
P = 7396 / (1 + 15/2 / 100)
= 7396 / (1 + 15 / 200)
P = 6880
Again principal for second installment will be
P = 7396 / [(1 + 15/200)^2]
P = 6400
Now P = 6880 + 6400
P = 13,280
Now interest paid will be 14,792 - 13,280 = Rs 1512
