Solution

The correct option is A 42
Number of vehicles parked in front of 1 corner gate = n
So, number of vehicles parked in front of 5 corner gate is 5 × n = 5n

Number of vehicles in front of the main gate = 12

So, the expression of total number of vehicles parked will be:
5n + 12

Now, the value of n is given as 6.

Putting this value in the expression, the total number of vehicles will be given by:


∴ Total number of vehicles parked is 42.
