A light shop sells lights, they sold 25 percent of the lights and still had 1500 lights left. How many Lights were there In the beginning?

2500

2250

2000

None of these

If they sold 25% of the lights, they have 75% of the lights left. We are given that 75% of the lights is 1500:

$0.75 x = 1500$

Solve for $x$ :

$x = 1500/$ 0.75

=2000

So, the total number of lights initially was 2000.
