The compound interest on a sum of money for 2 years is rs 615 and the simple interest for the same period is rs 600. What is the principal?
Rs.150
Rs.140
Rs.130
Rs.6000
Answer with explanation
Answer: Option DExplanation
Given :
Simple interest for two years = 600
Compound Interest for two years = 615
Analysis/Interpretation :
SI for first year = 300
SI for second year = 300
CI for first year = 300
CI for second year = 315
The additional CI of Rs 15 is interest on Rs 300 interest received in first year. So rate of interest is 15/300 x 100 = 5%.
Now, interest of Rs 300 at the end of first year @ 5% pa means principal at the beginning of the year is :
P = 300/5 x 100 = Rs 6000

The difference between compound interest and simple interest on an amount of Rs. 15,000 for 2 years is Rs. 96. What is the rate of interest per annum?
8
10
12
Cannot be determined
Answer with explanation
Answer: Option AExplanation
15000 x  1 +  R  2  – 15000  –  15000 x R x 2  = 96  
100  100 
15000  1 +  R  2  – 1 –  2R  = 96  
100  100 
15000  (100 + R)^{2} – 10000 – (200 x R)  = 96  
10000 
R^{2} =  96 x 2  = 64

There is 60% increase in an amount in 6 years at simple interest. What will be the compound interest of Rs. 12,000 after 3 years at the same rate?
Rs. 2160
Rs. 3120
Rs. 3972
Rs. 6240
Answer with explanation
Answer: Option CExplanation
Let P = Rs. 100. Then, S.I. Rs. 60 and T = 6 years.
R =  100 x 60  = 10% p.a.  
100 x 6 
Now, P = Rs. 12000. T = 3 years and R = 10% p.a.

A certain sum yields Rs 10110 in 6 years and Rs 6740 in 3 years on compound interest. What is the sum?
Rs 4500
Rs 4493
Rs 4490
Rs 4490
Answer with explanation
Answer: Option BExplanation
Let P be the sum to be found.
In 3 years, P(1 + r/100)^{3}= 6740 —— (1)
And, In 6 years, P(1 + r/100)^{6}= 10110—— (2)
Dividing both, we get,
(1 + r/100)^{3} = 10110/6740 = 3/2
Substituting this value in – (1)
P×(3/2) = 6740
P = 4493.33
