605 sweets were distributed equally among children in such a way that the number of sweets received by each child is 20 % of the total number of children. How many sweets did each child receive?

Correct answer: A. 11

  • A. 11
  • B. 24
  • C. 45
  • D. cannot be determined

Explanation

Let the number of children be n. Each child receives 20% of n = 0.2n sweets, so the total is n × 0.2n = 605; hence n² = 3,025 and n = 55 children. Each child therefore receives 0.2 × 55 = 11 sweets. Students may choose d because they do not form the equation linking the number of children with the sweets per child.
