Answer:
The correct number = 300
Step-by-step explanation:
Let 'x' be the number
It is given that, 20% of 'x' is 60 minutes.
To find expression of 20% 'x'
20% = 20/100 = 1/5
expression is 1/5(x)
To find x
20% of x is 60
Therefore, 1/5(x) = 60
x/5 = 60
x = 60*5 = 300
x = 300
Therefore the number is 300
