Answer 2

Given:

We have given the principal becomes 10050 at the rate of 10% in 5 years.

To Find:

We have to find the principal amount?

Step-by-step explanation:

• We have the total amount which is rupees 10050.
• The formula of simple interest is given by the

        $S.I=\frac{P\times R\times T}{100}$

• Now we know the total amount is given by the simple interest added by the principal amount.
• Let the principal amount be rupees x.
• We have the value rate of interest is R which is 10, Time which is T,5 years. Put these values in the formula of simple interest.

        $S.I=\frac{x\times10\times5}{100}$

• Now simplify the above equation we get

        $S.I=\frac{x}{2}$

• Now we know S.I+principal amount =total amount

        $\frac{x}{2} +x=10050$

• Now take the lcm of the above left-hand side and simplify the above equation.

        $\frac{3x}{2} =10050\\3x=10050\times2\\x=\frac{20100}{3}\\x=6700$

Hence,the principal amount is rupees 6700.
