Matt starts an 8-week routine program in increase his bench press. During the first two weeks, he increases his bench press by an average of 10 pounds per week, and during the last six weeks, he increases his bench press by an average of five pounds per week. If the total increase in the first two weeks is equal to the total increase of the last three weeks, by how many pounds had Matt increased his bench press after the fifth week of the routine?

• In the first two weeks total increase in pounds\(= 2\) x \(10 = 20\) pounds • In the last six weeks total increase in pounds \(= 6\) x \(5 = 30\) pounds • It is also given that,

o The total increase in last 3 weeks = total increase in first two weeks \(= 20 pounds\).

• Total increase in the (3rd,4th and 5th) week = Total increase in last six weeks - total increase in the last three weeks \(= 30 - 20 = 10\) pounds • Thus. total increase in the first five weeks = Total increase in the first two weeks + Total increase in the (3rd,4th,5th) weeks \(= 20 + 10 = 30\) pounds

Please correct me if I am wrong. In the question we have been by how many pounds had Matt increased his bench press after the fifth week of the routine? NOT average or total increase in first 5 months.

If average or total increase in first 5 months is equal to weight increase after the fifth week . Please help me understand how.

Bunnel it will be very helpful if you can also provide a solution.

Concentration: General Management, Entrepreneurship

GPA: 3.8

Bunuel I am really disappointed to see another wrong question in the Daily Practice question : 12-08-2017. Please try to filter out questions before putting it in Daily Practice Questions. Such questions if pops up on regular basis will spoil the usability of this section.

This question clearly asks that about the no. of pounds which Matt increased his bench press after 5th week of the routine , which means on 6th , 7th and 8th day combined and it is equal to 20

The solution or the answer is equivalent to the no. of pounds which Matt increased his bench press after 5th week of the routine first 5 days i.e. 30

People have posted solution considering 30 as Answer but we should solve question and then come to answer. We should not go otherwise.

Please change the question stem or the answer and I am sorry to say but this is not really a 700 level question..

Correct,

Got me confused too.

Question is asking for the increases in bench press AFTER the first 5 weeks and NOT within the 5 weeks period , the answer to the question as it is now should be 20 unless question is asking for the increase, during the first 5 weeks .

hope moderator will look into this !

Bunuel,

I agree with the last 2 posters-Answer should clearly be 20 .
