The grocery store parking lot will hold 100 vehicles. 2/5 of the parking spaces are for cars. When you went to buy groceries, there were 200 cars and some trucks in the parking lot. The parking lot was 3/4 full. How many trucks were in it?

Answer: 175.

Step-by-step explanation:

Since, Let there could be total number of vehicle parked = x

And, According to the question, 2/5 of the parking spaces are for cars.

Therefore, Number of cars are 2x/5

But, there were 200 car parked.

So 2x/5 = 200 ⇒x=500

That is, 500 vehicle can be parked in the parking lot.

And, Again from the question, The parking lot was 3/4 full.

The total vehicle that parked = 3/4 of 500 = 375

Therefore total number of buses = The total vehicle that parked - the total number of car that parked = 375-200=175.
