Question

Mohan lends Rs4800 to John for 9/2 years and Rs2500 to Shyam for 6 years and receives a total sum of Rs2196 as interest. Find the rate per cent per annum, it being the same in both cases .

Answer 1

Here,
For 9/2 years = Rs. 4800
So, for 1 year = 4800 * 9/2 = Rs.21600

For 6 years = Rs. 2500
So, for 1 year = 2500 * 6 = Rs. 15000
 Total for 1 year = Rs.36600

Interest = Rs. 2196
so, Rate /annul = 2196 * 100/36600 * 1 = 6%
