Answer 1

Answer:

C.I. = Rs.765

Sum = Rs.2081

Step-by-step explanation:

1.) C.I. = P{(1+i)^ n - 1}

Interest payable quarterly :

i = 8/4×100 = 0.02

n = 9/12×4 = 3 quarters

C.I. = 12500{(1+0.02)^3 -1}

=12500{(1.02)^3 - 1}

= 12500 (1.061208-1)

= 12500 ( 0.061208)

C.I = Rs 765

2.)C.I. = P{(1+i)^ n - 1}

328 = P { (1.05)^2 - 1}

328 = P (0.157625)

328\ 0.157625 = P

P = Rs. 2081 (2080.88)
