405 sweets were distributed equally among a group of children such that the number of sweets received by each child is one-fifth of the number of children. The number of children in the group is
1. 45
2. 9
3. 21
4. 15

Answer 1

Correct Answer - Option 1 : 45

Given:

Total number of sweets = 405

Formula used:

Total number of sweets = Total number of children × sweets received by each child

Calculation:

Let the number of children be n

Sweets received by each child = n / 5

⇒ n × n / 5 = 405

⇒ n² = 2025

∴ n = 45
