Q:

At a certain rate of interest the compound interest of 3 years and simple interest of 5 years for certain sum of money is respectively Rs. 1513.2 and Rs. 2400. Find the common rate of interest per annum ?

A) 5% B) 6%
C) 4% D) 3%
 
Answer & Explanation Answer: A) 5%

Explanation:

Given compound interest for 3 years = Rs. 1513.2

 

and simple interest for 5 years = Rs. 2400

 

Now, we know that  C.I = P1+R100n - 1

 

=> 1513.2 = P1+R1003 - 1 ...........(A)

 

And S.I = PTR/100

 

=> 2400 = P5R/100 ..................(B)

 

By solving (A) & (B), we get

 

R = 5%.
