Question

On what sum will be the compound interest at 5% per annum for 2 years compounded anually be rs 164?

Answer 1

$\huge\bold{Solution}$

$<b><i><u>$ Sum given below

let be = X 

✴Given as 

Rate = 5%
Time = 2 yrs
Compound Interest = 164

❇As we know that 

Compound Interest = Amount - Principal Amount 

164 = Amount - X 
Amount = 164+X 

Amount = (1+p R/ 100)^n

164 +X = x ( 1+ 0.05)²

164 +X = X + 1.10

164 = ( X +1.10)- x

164 = 0.1x

164 *0.1 =1640


Hence the Required Amount will be 1640

$\huge\boxed{Answer is 1640}$

Answer 2

Here is your solution

  given:-

let be X 


Rate = 5%
Time = 2 yrs
Compound Interest = 164

we know that 

Compound Interest = Amount - Principal Amount 

164 = Amount - X 
Amount = 164+X 


Amount = (1+p R/ 100)^n

Now

164 +X = x ( 1+ 0.05)²

164 +X = X + 1.10

164 = ( X +1.10)- x

164 = 0.1x

164 *0.1 =1640

Hence,
the Required Amount will be 1640
