15 post cards =Rs 7.50
therefore one postcard =(7.50 ÷ 15) =Rs0.50
therefore 36 postcards =(0.50×36) = Rs 18
————————————
no of postcards that can be bought in Rs 0.50 = 1
therefore no of postcards that can be bought in Rs 45 =(45÷0.50) = 90
therefore one postcard =(7.50 ÷ 15) =Rs0.50
therefore 36 postcards =(0.50×36) = Rs 18
