Question 72

If a deposit of Rs 2000 earns an interest of Rs. 500 in 3 years, how much interest would a deposit of Rs. 36000 earn in 3 years with the same rate of simple interest?

Answer 1

If deposit of Rs. 2000 earns in 3 yr with an interest = Rs. 500
Then a deposit of Rs. 1000 earns in 3 yr with an intereest $=\frac{500}{2}=250$
Similarly deposit of Rs. 3600 i.e. Rs. $36\times 1000$ earns in 3 yr with an interest $=250\times 36=Rs.9000$
