Correct Answer: 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.
Correct Answer: 45%
Explanation:
Let there be x voters and k votes goes to loser then
0.8x - 120 = k + (k + 200)
k+200 = 0.41x
=> k = 1440
and (k + 200) =1640
Therefore 1440/3200 x 100 = 45%
