Question

At the Cubs/White Sox baseball game on Sunday night, 65% of the fans were men. Another 25% were women. Of the remainder, 40% were boys and the rest were girls. If 640 boys attended the game, what was the total number of people in attendance?

Answer 1

Ok, 65% of the attendants were men, 25% were women.

That leaves us with 10% remaining. 

From those 10% .................The problem tells us that 40% are boys

So 10% * ( 0.4 ) = 4% ..............This means that 4% of the total attendants were boys.

So the distribution is

65%........men
25%........women
4%..........boys
6%...........girls

640 boys attended the game.....> this means that 4% of the total amount of people is 640.

So the number of persons that attended were

T= 100% *(640)) / 4% = 16000 people
