6.) A sum invested at the rate of interest 5% S.I grows to Rs. 5400 in 4 years. The same amount in 3 years at the rate of 10% per annum S.I will grow to

1. Rs. 5850
2. Rs. 5800
3. Rs. 5750
4. Rs. 5700

Let the sum be Rs. X

Amount = Rs. 5400

Number of years = 4

Rate of interest = 5% R = 10%

T = 3 years

P= Rs. 4500 7.) A sum of money at simple interest becomes Rs. 3000 in 2 years and Rs. 3540 in 5 years. Find the rate of interest.

1. 4 %
2. 4.5 %
3. 5%
4. 6%

After two years the amount is 3000 and in the next three years it becomes Rs. 3540.

So, we have:

P = Rs. 3000

Amount = Rs. 3540

Interest = 3540 - 3000 = 540

Number of years = 3 years

Rate of interest =? 8.) A moneylender charges Rs. 180 as simple interest on a sum of Rs. 600 for four months. What is the rate of interest per annum?

1. 80%
2. 85%
3. 90%
4. 95%

Principal = Rs. 600

Interest = Rs. 180 9.) A sum of money amounts to 3300 in 2 years and Rs. 3600 in 5 years. What is the principal amount?

1. Rs. 2700
2. Rs. 2850
3. Rs. 2950
4. Rs. 3100

After two years the amount is Rs. 3300 and in the next three years it becomes Rs. 3600.

Therefore, S.I for three years = 3600 -3300 = 300

S.I for one year = 300/( 3 ) = 100

S.I for two years = 100 * 2 = 200

Principal = 3300 - 200 = Rs. 3100

10.) An agent allows a rebate of 4% to an investor while the bank pays an interest of 14% on the investment. What is the actual rate of interest earned by the investor on his investment?

1. 18.75%
2. 18%
3. 17.75 %
4. 16%

Let the investor invests Rs. 100

Rebate given = 4%

So, the actual investment = 100 - 4 = 96

The bank pays interest of 14% on the investment which is Rs. 100 without rebate and Rs. 96 with rebate. Aptitude Simple Interest Test Paper 1
