Question

Answer

Given:
- The first number is 30% of a third number
- The second number is 40% of a third number

To find:
- What percentage is the first number of the second number

Solution:
Let the third number be x.

Then,
- The first number = 0.3x
- The second number = 0.4x

To find the percentage of the first number in the second number, we need to find (first number/second number) * 100

= [(0.3x)/(0.4x)] * 100

= 0.75 * 100

= 75%

Therefore, the first number is 75% of the second number.

Answer: Option D (75%)

Answer

D
