On account of the Republic day celebrations in a school, decorative items were distributed to students for the purpose of decorating their classroom. The decorative items were of three types namely balloons, balls and flags. Balloons come in packets of
50, balls come in packets of 32 and flags come in packets of 16. An equal number of decorative items of each type was purchased.
