Question

The difference between the Compound intrest and simple intrest on a certian sum for 2 years at 5% per annum is Rs.60 . find the sum​

Answer 1

Answer:

Slight correction, you are not after a solution but the value of an expression.

To evaluate your expression, I just need to use three simple points about logarithms, namely:

log(1)=0

log(a/b)=log(a)−log(b)

logn(n)=1

Answer 2

$\rm\underline\bold{Question \purple{\huge{\checkmark}}}$

The difference between the Compound intrest and simple intrest on a certian sum for 2 years at 5% per annum is Rs.60 . find the sum

$\huge{\tt{\colorbox{blue}{AnswEr:}}}$

Let the sum be P = Rs. 100.

time T = 2 years, rate of interest R = 5% per annum

Simple interest =  PRT/100= 100×5×2/100=

Rs 10

Compound amount= P( 1+R/ 100)^T

= 100×(1+5/100)²

= 110.25

Therefore the compound interest = compound amount - principal

= 110.25 - 100

= 10.25

the difference between the compound interest and simple interest

= 10.25 - 10.00

= 0.25

if the difference between the CI and SI is Rs. 0.25 the principal = Rs. 100

if the difference between the CI and SI is Rs. 60 the principal = (100/0.25)×60

= 24000

Thus The Sum Is Rs. 25000.

hope this helps you.
