  2. Too easy. It takes 2 hours for 1 worker to paint 1 wall. In 6 hours therefore 1 worker can paint 3 walls, hence you need 6 workers to paint 18 walls.

  5. Its 3 workers. Because 1 worker can paint one wall in 1 hr. So 3 workers can paint 18 walls in 6 hrs.

    6 is not the right answer.

  7. Logic:
    6 workers.
    So 2 workers paints 1 wall in 1 hour => in 6 hours they will complete 6 walls which is 3 times less than 18 =>
    for painting 18 walls in 6 hours needs 6 workers.
