Q.6 Shaina pays Rs 15000 as rent for 3 months. How much does she has to pay for a whole year, if the rent per month remains same?

Amount of rent paid in 3 months = Rs 7500
Amount of rent paid in 1 month = Rs 7500/3
Amount of rent paid in 12 months = Rs ( 2500 x 12) = Rs 30,000
Thus the required amount of rent paid in 1 year = Rs 30,000.
