Question

4. Radha lends 2500 to Meenal for 6 years and
4800 to Mannu for 4 years 6 months at the
same rate of interest. She receives a total interest
of 2196. Find the rate of interest.​

Answer 1

Answer:

si = prt/100

2196 = (2500*6*r)/100 + (4800*9*r)/100*2

2196 = 150r + 216r

2196 = 356r

6.16 = r
