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.
