Answer:
80 mugs of 450 ml each is needed to fill up a bucket of 36 litres.
Explanation:
Capacity of mug = 450 ml
Capacity of bucket = 36 litres
= (36 × 1000) ml [since, 1 litre = 1000 ml]
= 36000 ml
Therefore, number of mugs needed to fill the bucket = 36000/450
= 80
Hence, 80 mugs of 450 ml each is needed to fill up a bucket of 36 litres.
