Final answer:
To find the whole quantity when 60 represents 40%, we solve the equation 0.4 = 60/Whole, which results in a whole quantity of 150, indicating that the correct answer is not provided among the options.
Step-by-step explanation:
To determine the whole quantity when given that 60 is 40% of it, you use the formula for finding percentages:
Percentage (40%) = (Part/Whole) × 100
First, convert the percentage to a decimal by dividing by 100: 40/100 = 0.4.
Then, set up the equation where the part is 60 and solve for the whole:
0.4 = 60/Whole
To find the whole, divide both sides by 0.4:
Whole = 60 / 0.4
Whole = 150
So the whole quantity is 150, which means option 3) 30 is not the correct answer, and the correct answer is not listed among the options provided.
