Explanation:
20 men can do 1 W in 36 days
=> 20 men can do 1/36 W in 1 day
=> 10 men can do 1/72 W in 1 day.
30 girls can do 1W in 36 days
=> 30 girls can do 1/36 W in 1 day
=> 12 girls can do 1/90 W in 1 day.
Together 10 men and 12 girls can do 1/72 + 1/90 W in 1 day
= 9/360 = 1/40 W in 1 day.
Therefore they need 40 days to do the piece of work.
Answer: C In a 100-meter race, two of Amy's co-participants won Silver and Bronze and she performed exceedingly well; it follows that Amy won Gold.
Explanation:
There is a flaw in the evidence presented by the lawyer, several flaws actually:
- The client could have been the culprit and left the main door and garage open as an alibi.
- There is no mention of there being an altercation with a thief that cost the wife her life.
- There is no mention of things being stolen to prove that it was a thief.
The attorney used one logic and deduced a flawed conclusion from it so the option that is similar has to do the same as the above.
Option A is not applicable here as blame was taken by the perpetrator.
Option B is not flawed as one would be expected to be late in such circumstances.
Option C has a flaw because performing exceedingly well is relative. Amy could simply be performing exceedingly well in relation to past races. Amy's co-participants could have performed even better which is why they won medals and while Amy performed exceedingly well by her standards, it was not enough to win a medal.
Option D has no flaw. It is a logical deduction and argument just like option E.
