1.	Ram borrowed Rs.4800 from Sita at the rate of 10% per annum, at the end of one year.(i) How much simple interest will Ram have to pay? (ii) How much compound interest semi-annually will Ram have to pay ?
Answer» (i) S.I = (P x R x T) / 100 = (Rs. 4800 x 10 x 1) / 100 = Rs. 480 Rs. 480 Ram have to Pay. (ii) When Interest is semi-annually P = Rs.4800 R = 10% = 10%/2 = 5% T = 1 years = 1 x 2 years = 2 Years A = P(1+R/100)^t = Rs. 4800 ( 1+ 5/100)² = Rs. 4800 ( (100+5)/100)² = Rs. 4800 (105/100)² = Rs. 4800 x 105/100 x 105/100 = Rs. 5292 C. I = A - P = Rs. 5292 - Rs. 4800 = Rs. 492. Rs. 492 Compound interest semi-annually will Ram have to pay.

Ram borrowed Rs.4800 from Sita at the rate of 10% per annum, at the end of one year.(i) How much simple interest will Ram have to pay? (ii) How much compound interest semi-annually will Ram have to pay ?

Answer»

(i) S.I = (P x R x T) / 100

= (Rs. 4800 x 10 x 1) / 100

= Rs. 480

Rs. 480 Ram have to Pay.

(ii) When Interest is semi-annually

P = Rs.4800

R = 10% = 10%/2 = 5%

T = 1 years = 1 x 2 years = 2 Years

A = P(1+R/100)^t

= Rs. 4800 ( 1+ 5/100)²

= Rs. 4800 ( (100+5)/100)²

= Rs. 4800 (105/100)²

= Rs. 4800 x 105/100 x 105/100

= Rs. 5292

C. I = A - P

= Rs. 5292 - Rs. 4800

= Rs. 492.

Rs. 492 Compound interest semi-annually will Ram have to pay.
