Question

If the interest on Rs 3000 is Rs 600 at a certain rate for a certain number of years, what would the interest be on Rs 1500 under the same conditions? 

(A) Rs 300 

(B) Rs 1000 

(C) Rs 700 

(D) Rs 500

Answer 1

(A) Rs 300

The interest on Rs 3000 at certain rate of interest is Rs 600. 

Let us suppose the interest on Rs 1500 at the same rate is x. 

∴ 600/3000 = x/1500

∴ x = Rs 300
