In this question the result that will come will be a predicted result and so it might not be the perfect result. Now let us concentrate on the details that are already provided in the question.
It is given that 8 out of 19 players had 2 or more siblings
Then
Percentage of players having 2 or more siblings = (8/19) * 100 Percent
= 800/19 percent
Now assuming that the percentage does not change when surveyed among 570 players, then
Number of players having more than
2 siblings among 570 players = [800/(19 * 100] * 570
= (800/1900) * 570
= (8/19) * 570
= 8 * 30
= 240
So it can be predicted that 240 players will have 2 or more siblings. the second option given in the question is the correct option.
