Concept:If a car is at the exact centre, the number of cars on both sides is equal.Explanation:Maruti is 20th from the left end.Honda is 10 places to the right of Maruti.So Honda's position from the left is 20+10=30.Since Honda is exactly at the centre, there are 29 cars to its left and 29 cars to its right.Total cars = 29+1+29=59.
