In one hour, [tex]\frac{3}{4}[/tex] of the bucket gets filled.
What is unitary method?
'The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.'
According to the given problem,
In 20 minutes [tex]\frac{1}{4}[/tex] of bucket gets filled.
In 1 minute [tex]\frac{1}{4}[/tex] ÷ 20 of bucket gets filled.
= [tex]\frac{1}{80}[/tex] of bucket gets filled.
In 60 minutes, [tex]\frac{1}{80}[/tex] × 60 of bucket gets filled.
= [tex]\frac{3}{4}[/tex] of bucket gets filled.
Hence, we can conclude that in one hour [tex]\frac{3}{4}[/tex] of bucket gets filled.
