    Q1. A room is 4 meters 37 cm long and 3 meters 23cm broad. It is required to pave the floor with minimum square slabs. Find the number of slabs required for this purpose?

    • A) 485
    • B) 431
    • C) 391
    • D) 381

    Answer: 391

    Explanation: GCD(437, 323) = 19 cm (side of each square slab); number of slabs = (437/19) × (323/19) = 23 × 17 = 391.
