If a deposit of Rs. 2,000 earns an interest of Rs. 500 in 3 years, how much interest would a deposit of Rs. 36,000 earn in 3 years with the same rate of simple interest?

If deposit of ₹ 2000 earns in 3yr with an interest = ₹ 500

Then, a deposit of ₹ 1000 earns in 3yr with an interest =

Similarly, deposit of ₹ 3600 i.e. ₹ 36 × 1000 earns in 3yr with an interest = 250×36 = ₹ 9000
