From statement I:
Let the quantity of mixtures A, B, and C mixed be a liters, 3a liters, and 2a liters respectively.
From statement I and II:
⇒ a + 3a + 2a = 60
⇒ a = 10
Quantity of mixture A = 10 liters
Similarly, the Quantity of mixtures B and C is 30 liters and 20 liters respectively.
Quantity of water in the resultant mixture = 10 ×
+ 30 ×
+ 20 ×
= 15.5 liters
From statement III:
Let the quantity of water in three mixtures be 8m, 15m and 24m liters respectively.
We can't find the quantity of water using statement III.
∴ Using statements I and II we can answer the question.
