Question

find the compound interest accuring annually on ₹5000 for 3 years at the rate of 10 p.c.p.a find what the loan amounts to at the end of 2 years and 3 years?​

Answer 1

Answer:

interest.

No. Principal (₹) Rate (p.c.p.a.) Duration

(Years)

1 2000 5 2

2 5000 8 3

3 4000 7.5 2

ANSWER:

(1) Here, P = ₹ 2000; R = 5 % ; N = 2 years

A=P(1+R100)N =2000(1+5100)2 =2000(105100)2 =2000(2120)2 =2205 Rupees∴ Compound Interest after 2 years,I = Amount − Principal =2205−2000 =205 Rupees

Hence, Amount = ₹ 2205 and Compound interest = ₹ 205.

(2) Here, P = ₹ 5000; R = 8 % ; N = 3 years

A=P(1+R100)N =5000(1+8100)3 =5000(108100)3 =5000(2725)3 =6298.56 Rupees∴ Compound Interest after 3 years,I = Amount − Principal =6298.56−5000 =1298.56 Rupees

Hence, Amount = ₹ 6298.56 and Compound interest = ₹ 1298.56

(3) Here, P = ₹ 4000; R = 7.5 % ; N = 2 years

A=P(1+R100)N =4000(1+7.5100)2 =4000(1+751000)2 =4000(10751000)2 =4000(4340)2 =4622.50 Rupees∴ Compound Interest after 2 years,I = Amount − Principal =4622.50−4000 =622.50 Rupees

Hence, Amount = ₹ 4622.50 and Compound interest = ₹ 622.50
