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 scooters in the second half row.
Step-by-step Solution:
In the given question, Let C and S denote Cars and Scooters respectively,
Therefore, according to the question,
(C S C S S C S S S C S S S S C S S S)(S S C S S S S S S C S S S S S S S C)
Here both equal parts are divided by brackets.
It can clearly be seen that in the second half there are 15 Scooters. Therefore, Option A is the correct answer.
