Each of three investments has a 20% of becoming worthless within a year of purchase, independently of what happens to the other two investments. If Simone invests an equal sum J in each of these three investments on January 1, the approximate chance that by the end of the year, she loses no more than 1/3 of her original investment is Choose the correct choice from the following answers.
A) 90%  B) 80%  C) 70%  D) 60%  E) 40%

Solution: The problem asks for the approximate chance that no more than 1/3 of the original investment is lost. We can apply the “1 – x” technique: what’s the chance that more than 1/3 of the original investment is lost? There are two outcomes we have to separately measure:   (a) All 3 investments become worthless.   (b) 2 of the 3 investments become worthless, while 1 doesn’t.   Outcome (a): The probability is (0.2)(0.2)(0.2) = 0.008, or a little less than 1%.   Outcome (b): Call the investments X, Y, and Z. The probability that X retains value, while Y and Z become worthless, is (0.8)(0.2)(0.2) = 0.032. Now, we have to do the same thing for the specific scenarios in which Y retains value (while X and Z don’t) and in which Z retains value (while X and Y don’t). Each of those scenarios results in the same math: 0.032. Thus, we can simply multiply 0.032 by 3 to get 0.096, or a little less than 10%.   The sum of these two probabilities is   0.008 + 0.096= 
  0.008 + 0.096 = 0.104
0.104, or a little more than 10%. Finally, subtracting from 100% and rounding, we find that the probability we were looking for is approximately 90%.   The correct answer is A.   This problem illustrates the power of diversification in financial investments. All else being equal, it’s less risky to hold a third of your money in three uncorrelated (independent) but otherwise equivalent investments than to put all your eggs in one of the baskets. That said, be wary of historical correlations! Housing price changes in different US cities were not so correlated—and then they became highly correlated during the recent housing crisis (they all fell together), fatally undermining spreadsheet models that assumed that these price changes were independent.

A shipment of 1500 heads of cabbage, each of which was approximately the same size, was purchased for $600. The day the shipment arrived 2/3 of the heads were sold, each at 25% above the cost per head. The following day the rest were sold at a price equal to 8% less than the price each head sold for on the day before. What was the total gross profit on this shipment.  Choices.
A) $100  B) b $115  C) c $125  D) d $130  E) e $135

Solution: Purchase cost = 600/1500= 
600/1500 = 2/5 = around 0.4
$ 0.4   25% above the cost per head= (125/100)*0.4= 
(125/100)*0.4 = 0.5
$ 0.5   2/3 of the heads were sold means 2/3*1500= 
2/3*1500 = 1_000
1000 ,Selling amount for 1000 cabbage= 1000 * 0.5= 
1000 * 0.5 = 500
$ 500   Remaining were sold at a price equal to 8% less than the price each head sold for on the day before i.e , (92/100)*0.5= $ 0.46   Hence selling cost for the remaining cabbage = 500 * 0.46= 
500 * 0.46 = 230
$ 230   Total selling cost= 500 + 230= 
500 + 230 = 730
$ 730   Gross profit= $ 730 - $ 600 = $ 130   Hence Answer is d $130.

Solution: Solution: Average temperature for Wednesday, Thursday and Friday = 40oC   Total temperature = 3*40= 
3*40 = 120
120oC   Average temperature for Thursday, Friday and Saturday= 41oC   Total temperature = 41*3= 
41*3 = 123
123oC   Temperature on Saturday= 42oC   Now,   (Thursday + Friday + Saturday) - (Wednesday + Thursday + Friday) = 123-120;   Saturday - Wednesday = 3   Wednesday = 42-3= 
42-3 = 39

Machine R and machine B are each used to manufacture 660 sprockets. It takes machine R 10 hours longer to produce 660 sprockets than machine B. Machine B produces 10 percent more sprockets per hour than machine R. How many sprockets per hour does machine R produces?
Choose the correct choice from the following answers
A) 6	B) 6.6	C) 60	D) 100	E) 110

Solution: I think the correct answer is A.   Machine R produces at a speed of R sp/hour and B at a speed of B sp/hour.   so, 660/R=(660/B)+10 and B=1,1 R--->1,1*660=660+11R--->6=6, so answer 6 is correct

A student scored an average of 75 marks in 3 subjects: Physics, Chemistry and Mathematics. If the average marks in Physics and Mathematics is 90 and that in Physics and Chemistry is 70, what are the marks in Physics? Choose the correct choice from the following answers:
A) 86
B) 16
C) 76
D) 95
E) 26

Solution: Given M + P + C = 75 * 3= 
75 * 3 = 225
225 --- (1)   M + P= 90 * 2= 
90 * 2 = 180
180 --- (2)   P + C= 70 * 2= 
70 * 2 = 140
140 --- (3)   Where M, P and C are marks obtained by the student in Mathematics, Physics and Chemistry.   P= (2) + (3) - (1) = 180 + 140 - 225= 
180 + 140 - 225 = 95
