Connie has a number of gold bars, all of different masses. She gives the 17 lightest bars, which represent 30% of the total mass, to Brennan. She gives the 25 heaviest bars, which represent 48% of the total mass, to Maya. She gives the rest of the bars to Blair. How many bars did Blair receive?
The total mass of the gold bars is 100%. So, 30% of the total mass is 0.3 * 100% = 30%. This means that the 17 lightest bars have a total mass of 30%.
Similarly, the 25 heaviest bars have a total mass of 48%. So, the remaining 22% of the total mass is the mass of the bars that Blair received.
Since the mass of each bar is the same, the number of bars that Blair received is 22% / 1% = 22 bars.
Therefore, Blair received 22 bars.
You are absolutely full of Intentional moronic bullshit, WAT (Wrong Answer Troll).
Since the mass of each bar is the same <--- This statement is proof you intentionally answered this wrong.
The question clearly says, Connie has a number of gold bars, all of different masses
You are an unethical and destructive asshole!

Here’s a descriptive solution for this problem:
---
Let B = the total number of bars.Then 0.30(B)=17(lightest bars)|B=170.30≈56 total bars 0.48(B)=25 (heaviest bars)|B=250.48≈52 total bars Weighted average estimate of total number of bars: (17∗56+25∗52)(17+25)≈54 bars Fraction of total mass remaining:(0.22)0.22(54)≈12 bars Total bars: 54Blair receives 12 of the 54 bars.
