Q.12. A vessel has 4 litres and 500 ml of curd. In how many glasses, each of 25 ml capacity, can it be filled?

Quantity of curd in the vessel
= 4 l 500 ml = 4 × 1000 + 500 = 4500 ml
Capacity of 1 glass = 25 ml
\(\therefore \)Number of glasses that can be filled with curd = \(\ftac{4500}{25} \) = 180 glasses
