Drum X is 12 full of oil and Drum Y, which has twice the capacity of Drum X, is 23 full of oil. If all of the oil in Drum X is poured into Drum Y, then Drum Y will be filled to what fraction of its capacity?

11/12 full

Explanation:

The correct question is

Drum X is 1/2 full of oil and drum Y, which has twice the capacity of drum X, is 2/3 full of oil. If all of the oil in drum X is poured into drum Y, then drum Y will be filled to what fraction of its capacity?

A) 3/4

B) 5/6

C) 11/12

D) 7/6

E) 11/6

Solution

Let Capacity of Drum X = 150L

and Drum Y = 300L

Oil in Drum X = 75 L

Oil in Drum Y = 2/3 * 300 = 200L

Oil poured in to Drum Y => Oil in Drum Y = 275L

Capacity Ratio = 275/300 = 11/12

- decrease the number of plants and animals living in the water.
