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?
Rent paid for 3 months = `7500 RS.
∴ Rent paid for 1 months = \(\frac{7500}{3}\) = 2500
∴ Rent paid for 12 months = 2500 x 12 = 30,000 Rs.
Thus, the total rent of one year is 30,000 Rs.
