HOPE THIS ANSWER WILL HELP YOU AND MARK ME AS BRAINLIST
⇒ Given:
The difference between simple interest and compound interest at the rate of 10% for two years on an amount is rs.20.
⇒ To Find:
The principal amount.
⇒ Solution:
We have to solve the simple and compound interest values separately.
Let's assume the value of principal amount as "p".
Formula used:
It is given that:
✳ Rate of interest = 10%
✳ Time = 2 years
Substituting these values in the equation:
The simple interest is 20p/100.
Formula used:
Writing the formula in equational format:
It is given that:
✳ Rate of interest = 10%
✳ Time = 2 years
Substituting these values in the equation:
The compound interest is 21p/100.
Now, it is given that:
Substituting the values in the equation:
The principal amount is Rs. 2000.
