Question

The difference between the compound interest and simple interest on a certain sum for 2 years at 20%per annum is rs.40 then, the sum is​

Answer 1

Answer:

Explanation: If Diff. between SI & CI for 2 years is Rs. x, then Principal = x (100/r)2 P = 50 x (100x100)/(10x10) → P = 5000.

Answer 2

Step-by-step explanation:

Let the principal be x

rate= 20%= 0.20

time= 2 years

Amount= Principal $(1 + rate)^{time}$

Amount= 1.44x

Compound interest= Amount-interest= 1.44x-x= 0.44x

Simple Interest= $\frac{Principal*Rate*Time}{100}$

Simple Interest=$\frac{x*20*2}{100}$

Simple Interest= 0.4x

The difference between simple interest and compound interest on a certain sum of money at 20% per annum for 2 years is 40

0.44x-0.4x= 40

0.04= 48

So,

x= $\frac{40}{0.04}$

x= 1000 is the right answer.
