Question

Understand the Question

The Food Court serves as the reference point or starting level ( $0$ ).
Pressing $+2$ in the lift indicates moving $2$ floors upward in the positive direction.
By counting $2$ floors up from the Food Court, we determine the final destination.

Step 1 · Identify the Starting Floor

From the building floor layout, the starting point is the Food Court, which represents floor $0$ . Diagram 1

Step 2 · Move Upward by 2 Floors

Pressing $+2$ means moving up $2$ floors from floor $0$ :

Moving up $1$ floor from Food Court (floor $0$ ) leads to the Art Centre (floor $+1$ ).
Moving up $1$ more floor leads to the Books section (floor $+2$ ).

$0 + 2 = 2$

Thus, the final floor reached is the Books section.

Answer

Books

Common Mistakes

Direction Error: Confusing $+2$ (moving upwards) with $-2$ (moving downwards below ground level).
Counting Error: Counting the starting floor as $1$ instead of $0$ , which incorrectly leads to the $+1$ floor (Art Centre).
