Answer 1

Answer:

( i ) Amount = Rs. 11, 241. 25

Interest = Rs. 2, 741. 25

( ii ) Amount = Rs. 23, 152. 50

Interest = Rs. 3, 152. 50

Step-by-step explanation:

When a sum is borrowed at compound interest,

A = P [ 1 + ( R / 100 ) ] ^n

A = amount

P = principal

R = rate

n = Time

As per the given information,

( i ) A = 8500 [ 1 + ( 15 / 100 ) ] ^2

A = 8500 [ 1 + ( 3 / 20 ] ^2

A = 8500 [ 23 / 20 ] ^2

A = 8500 [ 529 / 400]

A = Rs. 11, 241. 25

C. I. = A - P

C. I. = 11, 241. 25 - 8500

C. I. = Rs. 2, 741. 25

( ii ) A = 20000 [ 1 + ( 5 / 100 ) ] ^3

A = 20000 [ 1 + ( 1 / 20 ) ] ^3

A = 20000 [ 21 / 20 ] ^3

A = 20000 [ 9261 / 8000 ]

A = Rs. 23, 152. 50

C. I. = A - P

C. I. = 23, 152. 50 - 20, 000

C. I. = Rs, 3, 152. 50
