Hi everyone,
It usually takes me a lot of time (2-4 mins) in solving Distance speed and work rate questions. I do them by creating DST table and then solving equations. How do you guys do it fast? In some solutions and videos I saw people taking ratios and solving but I am having trouble thinking and solving like that. Any suggestions??

Critical Reasoning Butler: August 2025

_____________________________________
CR 1

A proposal for a new building fire safety code requires that fireretardant insulation no longer be sprayed on steel girders in the factory, but be sprayed on once the girders have arrived at the building site. This will eliminate the dislodging of the insulation in transit and reduce fatalities in catastrophic fires by an estimated 20%.

Which of the following, if true, represents the strongest challenge to the new proposal?

(A) The fire-retardant insulation will also be required to be one inch thicker than in the past.

(B) Studies have shown that most dislodgement of insulation occurs after the girders arrive on site.

(C) Catastrophic fires represent only 4% of the fires reported nationally.

(D) The proposed safety code will add considerably to the cost of new construction.

(E) In most of Europe, spraying fire-retardant insulation onto steel girders at the building site has been required for the past ten years.
_____________________________________
CR 2

In order to understand the dangers of the current real-estate bubble in Country Y, one has only to look to the real-estate bubble of the last decade in Country Z. In that country, incautious investors used the inflated value of their real estate as collateral in risky margin loans. When the real-estate market collapsed, many investors went bankrupt, creating a major recession. Country Y is in real danger of a similar recession if more stringent laws restricting margin loans are not enacted promptly.

The answer to which of the following questions would be most useful in evaluating the significance of the author’s claims?

(A) Was the real estate in Country Z located principally in rural areas or was it located in more urban communities?

(B) Could the bankruptcies in Country Z have been prevented by a private bailout plan by the nation’s banks?

(C) Does Country Y currently have any laws on its books regarding margin loans?

(D) Are there business ties and connections between Country Y and Country Z?

(E) Were there other factors in the case of Country Y that would make the comparison with Country Z less meaningful?

If a + b = 9c, and the average (arithmetic mean) of a, b, c, and d in terms of c is 4c, then what is d in terms of c?

A. c/3
B. 2c
C. 5c/2
D. 5c
E. 6c

What is the maximum possible value of the mean of three distinct single digit integers?

A. 6
B. 7
C. 8
D. 8.5
E. 9
PS 1.

a+b+c+d/4 = 4C

Means we can say each should have 4C ...So... there are a total of 16C....
Now a+b is already 9C and then there is 1c meas a total of 10c... we need 16c ... Answer E...

Alternate logic
Can also do like this.. if each needs a value of 4C...
Then an and b together has 1 extra c and C has 3 less C.. so in a total 2 less C.. now D needs to have the 4 C of itself plus the extra 2C that a b c are lacking.

So E.

———

PS... 2

Three distinct single integers with max value are 7,8,9 means Mean should be 8

Answer C.

DS1

No of seats on Tuesday... we are only given that half were full...

Let total be 2x... therefore half were x

Statement 1. 6x/5=6*2x/10

Gives the same equation ... not sufficient


Statement 2.
X+20 = 54*2x/100 - Suff
Also.. if we know 4% is 20... we can find out how much is 50%.. hence Suff
