Understanding the Problem
To find 72% of a number based on the given information, we start by defining the unknown number as 'x'. The problem states that the difference between 42% of this number and 23% of the same number equals 304.
Setting Up the Equation
We can express this mathematically:
- 42% of x = 0.42x
- 23% of x = 0.23x
The difference between these two percentages can be set up as:
0.42x - 0.23x = 304
Simplifying the Equation
Now, simplify the left side:
- 0.42x - 0.23x = 0.19x
Thus, the equation becomes:
0.19x = 304
Finding the Value of x
To find 'x', divide both sides by 0.19:
x = 304 / 0.19
Calculating this gives:
x = 1600
Calculating 72% of x
Now, we need to find 72% of the number:
- 72% of x = 0.72 * 1600
Calculating this:
0.72 * 1600 = 1152
Conclusion
Therefore, 72% of the number is 1152, which corresponds to option 'D'.

Let the number be 100x.
∴ 42x - 23x = 304
=> 19x = 304
=> x = 16
∴ The number is 100 x 16 = 1600.
=> 72% of the number = 0.72 x 1600 = 1152
