Question

A vessel of capacity 80 litres, is filled with milk and water. 70% of milk and 30% of water is taken out of the vessel. It is found that the vessel is vacated by 55%. The initial quantity of milk and water was?

• A. 50 litres and 35 litres
• B. 50 litres and 30 litres
• C. 50 litres and 40 litres
• D. 50 litres and 45 litres
• E. None of these

Answer 1

The correct option is B 50 litres and 30 litres

Here, the % values of milk and water that is taken from the vessel should be taken into consideration.
$\Rightarrow 5:3$
Ratio of milk to water =5 : 3
So, quantity of milk $=\frac{80}{8}\times 5=50litres$
and quantity of water $=\frac{80}{8}\times 3=30litres$
