405 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 recieve ?
A) 9
B) 10
C) 11
D) 12
Answer: A) 9
Explanation:
Let the total number of children be x.
Then, x * (20% of x) = 405
=> x * 20x/100 = 405
= 405
=> x=45
Number of sweets received by each child = 20% of 45 = 9.
