The difference between CI and SI on a sum of money lent for 2 years at 10% is Rs. 40. The sum is : Let, P = 100x SI = (100×R×T) / 100 SI = (100×10×2) / 100) SI = 20x

A sum of Rs. 2400 deposited at CI, doubled after 5 years. After 20 years it will become : Solution - Given, A = 4800 P = 2400 T = 5 A = P (1 + (r/100))n 4800

The CI on Rs. 5000 for 3 years at 8% for first year, 10% for second year and 12% for third year will be : Solution - Given, P = 5000 R = 8% for first year, 10% for second year

Rs. 6000 amounts to Rs. 7986 in 3 years at CI. The rate of interest is : Solution - Given, A = 7986 P = 6000 T = 3 years R = ? A = P (1 + (r/100))n 7986 = 6000 (1 + (r/100))3

At compound interest, if a certain sum of money doubles in n years, then the amount will be four fold in : Solution - Given, A = 2P A = P (1 + (r/100))n 2P = P (1 + (r/100))n 2

A sum of Rs. 400 would become Rs. 441 after 2 years at r% compound interest, find the value of 'r' : Solution - Given, P = 400 A = 441 R = r% T = 2

The compound interest on Rs. 5000 at 30% per annum in 4 years is : Solution - Given, P = 5000 R = 30% T = 4 A = P (1 + (r/100))n A = 5000 (1 + (30/100))4 A = 5000 ((13/10))4

The compound interest on Rs. 4000 at 25% p.a. in 3 years is : Solution - Given, P = 4000 R = 25% T = 3 A = P (1 + (r/100))n A = 4000 (1 + (25/100))3

The compound interest on Rs. 10000 at 20% p.a. in 4 years is : Solution - Given, P = 10000 R = 20% T = 4 A = P (1 + (r/100))n A = 10000 (1 + (20/100))4 A = 10000 ((12/10))4

The compound interest on Rs. 1000 at 10% p.a. in 3 years is : Solution - Given, P = 1000 R = 10% T = 3 A = P (1 + (r/100))n A = 1000 (1 + (10/100))3

Find the amount of Rs. 1700 invested at 16% half yearly at simple interest for one year : Solution - Given, P = 1700 R = 16% T = 2 (half yearly at simple interest for one year) So,

Find the amount of Rs. 2500 invested at 12% during the period from 4th February, 2005 to 18 April 2005 : Solution - Given, P = 2500 R = 12% T = Feb + March + April

Pratibha invests an amount of Rs. 15,860 in the names of her three daughters A, B and C in such a way that they get the same interest after 2, 3 and 4 years respectively.

A lends a sum of money for 10 years at 5% SI. B lends double the amount for 5 years at the same rate of interest. Which of the following statements is true in this regard?

A person takes a loan of Rs. 200 at 5% simple interest. He return Rs. 100 at the end of 1 year. In order to clear his dues at the end of 2 years, he would pay :

Akul lent Rs. 6000 to Bakul for 2 years and Rs. 1500 to camlin for 4 years and received altogether from both Rs. 900 as simple interest. The rate of interest is :

A sum of Rs. 2500 is lent out in two parts, one at 12% p.a. and another at 12.5% p.a. for one year. If the total annual income is Rs. 306, the money lent at 12% is :

Out of a sum of Rs. 625, a part was lent at 5% SI and the other at 10% SI. If the interest on the first part after 2 years is equal to the interest on the second part after 4 years

A sum of money doubles itself in 12 years. In how many years would it treble itself ?

A sum of money triples (i.e., 3 times) in 15 years at r% of simple interest per annum. What is the value of r? Solution - Given, Principal = P Amount = 3P

At r% per annum a sum doubles after 20 years. The rate of interest per annum is : Solution - Given, Principal = P Amount = 2P (double itself) S.I = Amount - Principal

In what time will a sum of money double itself @ 20% per annum (p.a) simple interest? Solution - Given, Principal = P Amount = 2P (double itself) S.I = Amount - Principal

A sum was put at simple interest at a certain rate for 2 years. Had it been put at 4% higher rate, it would have fetched Rs. 112 more. The sum is :

If the rate of simple interest is 12% per annum, the amount that would fetch interest of Rs. 6000 per annum is : Solution - Given, R = 12% T = 1 S.I = 6000 P = ?

What is the sum of amount which gives Rs. 6300 as interest @ 7% per annum of simple interest in 7(1/2) years? Solution - Given, S.I = 6300 P = ? T = 7(1/2) R = 7%

What is the rate of simple interest at which Rs. 14,000 gives interest of Rs. 1960 in two years? Solution - Given, S.I = 1960 P = 14,000 T = 2 R = ? S.I = (P×R×T) / 100

What is the time period for which Rs. 8000 amounts to Rs. 12000 at 20% p.a. of simple interest? Solution - Given, P = 8000 R = 20% T = ? S.I = 12000 - 8000 S.I = 4000

A man borrrows Rs. 4000 and pays back after 5 years at 15% simple interest. The amount paid by the man is : Solution - Given, P = 4000 R = 15 T = 5 S.I = (P×R×T) / 100
