Four families decided to go watch a movie on a Friday evening. The Rahmans (R) have 5 family members, the Khans (K) have 3, Sarkars (S) 2, and the Hasans (H) 2. They buy a movie-ticket for each member. During the intermission, R goes to the concession-stand and buys 5 large popcorns. K buys 2. S and the H buy 1 and 0 respectively. Once the movie ends, the families go to an ice-cream parlour nearby. R orders 4 scoops of ice-cream and 2 coffees. K orders 2 scoops of ice-cream and 3 coffees. S orders 4 scoops of ice-cream and 2 coffees. H orders 1 scoops of ice-creams and 2 coffees. At the end of the night, the total expenditure of the families are as follows: The Rahmans have spent Tk. 5064; the Khans have spent Tk. 2896; the Sarkars have spent Tk. 2889; and the Hasans have spent Tk. 1518.
