The difference 40% of a number and 25% of the same number is 75. What is 30% of the number?
किसी संख्या का 40% और उसी संख्या का 25% का अंतर 75 है। उस संख्या का 30% कितना होगा?
Detailed Solution & Logic
Correct Answer:
150
Let the number be $x$.
Given:
40% of x - 25% of x = 75
$\frac{40}{100}x - \frac{25}{100}x = 75$
$\frac{15}{100}x = 75$
$x = \frac{75 \times 100}{15} = 500$
Now, 30% of $x$ = $\frac{30}{100} \times 500 = 150$
Answer: 150
