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

Capacity of vessel = 4 l 500ml

1 l = 1000 ml

4 l 500 ml = 4500 ml

Capacity of a glass = 25 ml

Number of glasses required to fill the vessel = 4500÷25

So,

180 glasses needed to fill the vessel.
