  1. 11
  2. 18
  3. 19
  4. 20
Explanation
Answer: C - 48 divided by 2 ½ = 48 divided by 5/2 = 48÷5/2 = 48 x 2/5 = 19.2
19 pieces of 2 ½ foot each. The 20th piece will be of smaller size.

Key takeaway: Division by 10 is easy. So if you have to divide by 2 ½, first divide the number by 10 and then multiply by 4
