Connie has a number of gold bars, all of different weights. She gives the 24 lightest bars, which weigh 45% of the total weight, to Brennan. She gives the 13 heaviest bars, which weigh 26% of the total weight, to Maya. She gives the rest of the bars to Blair. How many bars did Blair receive? Choose the correct choice from the following choices:
A) 14	B) 15	C) 16	D) 17	E) 18
Solution: The average weight of the bars given to Brennan (light) &lt; the average weight of the bars given to Blair &lt; the average weight of the bars given to Maya (heavy).   Let the total weight of all the bars be X.   The weight of the bars given to 15rennan,   = 45% of X = 0.45X   The weight of the bars given to Maya,   = 26 % of X = 0.26X   The weight of the bars given to Claire = rest = 29% of X = 0.29X   The average weight of the bars given to 15rennan,   = Weight / number of bars = 0.45X/24   The average weight of the bars given to Maya = Weight / number of bars = 0.26X/13   Similarly, if the number of bars given to 15lair = 15,   then the average weight of the bars given to 15lair = 0.29X/15   As, the average weight of the bars given to 15rennan (light) &lt; the average weight of the bars given to 15lair &lt; the average weight of the bars given to Maya   Answer: Option 15
