Question
In a colony, there are 90 APL families and 46 BPL
families. Each APL and BPL family got blankets equal to 25% and 75%, respectively of total number of families (APL + BPL) in the colony. Find the difference between total number of blankets received by APL and BPL families.Solution
Total number of families in the colony = 90 + 46 = 136 Number of blankets received by APL families = 90 x 0.25 x 136 = 3060 Number of blankets received by BPL families = 46 x 0.75 x 136 = 4692 Required difference = 4692 - 3060 = 1632
