In a row of vehicles, a car is 20th from the left end. A bike is 10th to the right of the car and is at the exact centre of the row. How many vehicles are there in the row?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 59
A vehicle at the exact centre has the same position from both ends, so total = 2 × its position − 1.
The bike is 10th to the right of the car: \(20+10=30\)th from the left
At the centre it is also 30th from the right
Vehicles in the row \(=30+30-1=59\)
