Question

In a parking lot there are two types of vehicles, two wheelers and four wheelers. The total number of the vehicles in the parking lot is 200. When the number of the wheels of all the vehicles is counted it is counted to be 580. Find the total number of the four wheeler vehicles in the parking lot ?
A) 110
B) 90
C) 100
D) 180

Answer 1

Answer is B

Total number of vehicles = 200

Total number of wheels = 580

Let the number of 4 wheeler be $x$, then number of 2-wheelers = $200-x$.

According to the question,

$4x + 2(200-x) = 580$

⇒ $2x$ = $180$

⇒ $x$ = $90$

∴ Number of four wheelers is 90
