Question

Two and a half times a number is 500. What is the number?

Answer 1

Answer:

x = 2750

Step-by-step explanation:

5$\frac{1}{2}$ × x = 500

$\frac{11}{2}$x = 500

x = 500×$\frac{2}{11}$

x = 2750

Answer 2

Let, the number be x.

So, 2 1/2 of x is 5/2x.

According to the given condition

⇒ 5/2x = 500

⇒ 5(500) = 2x

⇒ 2500 = 2x

⇒ 1250 = x

The number is 1250.
