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

Capacity of curd in a vessel = 4 liters 500 ml = 4 × 1000 ml + 500 ml = 4500 ml

Capacity of one glass = 25ml

Number of glasses can be filled = 4500/25

Therefore, 180 glasses can be filled by curd.
