Question : If 50 percent of a number is 80, then what will be the 250 percent of that number?
Option 1: 400
Option 2: 360
Option 3: 440
Option 4: 480
Correct Answer: 400
Solution :
Given: 50 percent of a number is 80.
Let the number be $x$.
According to the question,
$\frac{50}{100}\times x=80$
⇒ $x = 160$
The 250 percent of that number = $\frac{250}{100}\times 160=400$
Hence, the correct answer is 400.
