Formula (Question: 191691.0 )

what is exactly the formula for
SI/CI..... would it be 200 always?

Question:

The compound interest on a sum for 2 years is Rs. 832 and the simple interest on the same sum at the same rate for the same period is Rs. 800. What is the rate of interest ?

Options:
A) 6%
B) 8%
C) 10%
D) 12%
Solution:
Ans: (b)



alternate sol:


Given that simple interest for 2 years is Rs.800


i.e., Simple interest for 1st year is Rs.400

and simple interest for 2nd year is also Rs.400


Compound interest for 1st year will be 400

and Compound interest for 2nd year will be 832 - 400 = 432


you can see that compound interest for 2nd year is more than simple interest for 2nd year by 432 - 400 = Rs.32 


i.e, Rs. 32 is the interest obtained for Rs.400 for 1 year


Rate, R = 100×SIPT =100×32400×1 =8%

see ,how formula is derived.
CI/SI=P[(1+R/100)^2-1]/ (2*P*R)/100...
calculate the above equation and get the formala.
