Question 80

A sum fetched a total simple interest of Rs. 9648 at the rate of 12% per year in 6 years. What is the sum?

Solution

Let the sum = $$Rs. 100x$$

Rate = 12% under simple interest and time = 6 years

=> Simple interest = $$\frac{P \times R \times T}{100}$$

=> $$\frac{100x \times 12 \times 6}{100}=9648$$

=> $$72x=9648$$

=> $$x=\frac{9648}{72} = 134$$

$$\therefore$$ Sum = $$100 \times 134 = Rs$$ $$13,400$$

=> Ans - (D)
