Answer:
The drum capacity is 180 liters.
Step-by-step explanation:
Let the capacity of the drum be c. Then the contents of the drum at the beginning are (3/4)c, and
if 30 liters are drawn out, then the contents are (3/4)c - 30 liters = (7/12)c.
Here the LCD is 12, and so we have (9/12)c - (7/12)c = 30 liters, or
(2/12)c = 30 liters, or c = (12/2)(30 liters) = 180 liters
The drum capacity is 180 liters.
