A&B borrowed rs.3500 & rs.4000 respectively at the same rate of interest for 2 and a half years. If b paid rs.150 more than a, find the rate

Answers (1)

As it is not mentioned we assume it is a simple interest.

4000xRx2.5/100 - 3500xRx2.5/100 = Rs 150

(10000 - 8750)xR/100 = 150 
        
Interest Rate (R) = 150x100 /1250 = 12%
