Question 121

Arjun borrowed some money at the rate of 9% per annum for the first 3 years, at the rate of 6% per annum for the next 2 years and at the rate of 14% for next 4 years. If he pays a total simple interest 2280, how much did he borrow?

Solution

Let the amount borrowed by Arjun be x.
SI = $$\frac{PRT}{100}$$
Given,
$$\frac{9*x*3}{100} + \frac{6*x*2}{100}+\frac{14*x*4}{100} = 2180$$
$$\frac{95*x}{100} = 2280$$
x = 2400
