Question

At a paint shop, there were some identical pails. 60% of the pails were completely filled with paint. 32% of the pails were 1/3 filled with paint.
The remaining 20 pails were empty. The total amount of paint in the pails was 1590 ℓ.
(a) How many pails were completely filled with paint?
(b) What was the amount of paint in one full pail?

Answer 1

Empty pails = 8% x = 20 pails
x = 20 * 100/8
Total pails = 250 pails
60% pails = 150 pails
32% pails = 80 pails
(1) How many pails completely filled with pails?
150 pails
(2) Amount of paint in one full pail?
150 + 80/3 = 1590 ℓ
9 liters
