A first class stamp costs 26c, a second class stamp costs 21c. I buy some stamps and the cost is $1.93. How many of each price have I bought?
(193 - (21×a))/ 26 { for a =(1 - 9) } should give us an integer value. This happens at a=3 (193 - (21×3))/ 26 = 5 Which means: (21c × 3Nos) + (26c × 5Nos) = 193c ie.,He bought 3 Nos of 21 cents stamp and 5 Nos of 26 cents stamp.
