Dear Sir/Mam,
How to solve Compound Variation Questions.
For Example: If 120 children consume 300 LT of milk in 30 days, how many days do 30 students children consume 540 litres of milk?
Please explain an easy method to solve these kinds of questions.

Expert Answer
Milk consumed by 1 child = 300/(120 x 30) = 0.083 litres
Let 30 students consume 540 litres of milk in 'x' days
Therefore, 0.083 = 540/(30x)
Therefore, x = 216
So, 30 students consume 540 litres of milk in 216 days.
