Answer 2

Answer:

The answer is Rs. 2.50

Step-by-step explanation:

Rahul:

Amount(compounded yearly) = P(1+r/100)^n=

1000( 1 + 10/100)^1 =

1000(110/100) = Rs. 1100

Therefore, compound interest = Rs. 100

Sunil:

Amount(compounded half - yearly) = P(1+r/200)^2n =

1000(210/200)^2 =

1000 * 441/400 = 4410/4 = 1102.5

Therefore, amount = Rs. 1102.5

Therefore, compound interest = Rs102.5

Therefore, difference = 102.5 - 100 = Rs 2.5
