Sample Problem

The total capacity of 4 pails and 6 basins is 48.8 liters. If the capacity of each pail is 1.2 liters more than the capacity of each basin, what is the total capacity of 5 such pails?

  liters

Solution

Pretend that each basin is a pail. This means there would be 6 more pails, so there would be a total of 10 pails that add a capacity of 1.2 × 6 = 7.2 liters to the total.

The total capacity of the 10 pails would then be 48.8 + 7.2 = 56 liters.

Therefore, the capacity of each pail is 56 ÷ 10 = 5.6 liters.

So, the total capacity of 5 such pails is 5.6 × 5 = 28 liters.
