Question 140

The difference between C I and S I for 2 years at 10% rate of interest is Rs. 4. Find the sum of money.

Solution

Let sum of money = Rs. $$P$$ and rate of interest = $$R=10\%$$

Difference (for 2 years) = $$\frac{PR^2}{(100)^2}$$

=> $$\frac{P\times10\times10}{10000}=4$$

=> $$P=4\times100=Rs.$$ $$400$$

=> Ans - (A)
