Question:

Sulyn filled two types of pails, large and small, with some red paint that she had bought. She filled 3 identical large pails and 4 identical small pails to the brim with 10.1 L of red paint.

She could not fill another large pail to the brim with the remaining amount of red paint as she was short of 0.3 L of red paint. Hence, she filled another small pail to the brim and had 0.5 L of red paint left.

(a) How many more litres of red paint can each large pail hold than each small pail?
(b) How many litres of red paint did Sulyn buy?
