Answer 1

He had a large container of 25 quarts. Then he used 25 quarts and 35.9% of the oil remained.
100% - 35.9% = 64.1%
25 quarts ------------------------- 64.1%
 x quarts  -------------------------- 100%
------------------------------------------------
25 : x = 64.1 : 100
64.1 x = 2,500
x = 2,500 : 64.1 = 39.00156 ≈ 39 quarts
39 - 25 = 14 quarts
Answer: 14 quarts of olive oil remained in the container.
