Question

mohan lends rs.4800 to john for 4.1/2 years and rs.2500 to shyam for 6 years and recieves a total sum of rs.2196 as interest. Find the rate percent per annum,it being the same in both the cases​

Answer 1

Answer:

let simple interest for mohan = x

for shyam= 2196 - x

for mohan

x = 4800x 9x r / 200

for shyam

2500x 6x r/100 = 2196 - x

x = 2196 - 150r

216r = 2196 - 150r

366r = 2196

r = 6 %
