Thirty-six vehicles are parked in a parking lot in a single row. After the first car, there is one scooter. After the second car, there are two scooters. After the third car, there are three scooters and so on. Work out the number of scooter in the second half row.
Explanation
There are 15 scooters in the second half of the row. The parking arrangement is a series of cars followed by an increasing number of scooters (C, S; C, SS; C, SSS, etc.). By counting the total vehicles until the 7th car, which completes 28 scooters, the arrangement reaches 35 vehicles (7 cars + 28 scooters). The 36th vehicle is the 8th car, and it's placed after the 7 scooters. The row is divided into two halves of 18 vehicles, and 15 scooters are found within the second half.
