Four staff members at a certain company worked on a project. The amounts of time that the four staff members worked on the project were in the ratio 2 to 3 to 5 to 6. If one of the four staff members worked on the project for 120 hours, which of the following CANNOT be the total number of hours that the four staff members worked on the project? Choose one:	A) 384	B) 320	C) 960	D) 192	E) 640

Solution: Four members worked in ration 2:3:5:6, hence as everyone mentioned, individual work could be taken as 2x, 3x,5x, and 6x. Also this gives us total work as 16x.   But we are told that one of these individual works is 120hrs. hence, possible scenarios, if   (1)2x =120 => 16x = 960 (2) 3x =120 => 16x = 640 (3) 5x =120 => 16x = 384 (4) 6x =120 => 16x = 320   Hence Answer is 192 192 which can not be any of these.

A train travelled at an average speed of 100 km/hr, stopping for 3 minutes after every 75 km. How long did it take to reach its destination 600 km from the starting point?	Choose the correct choice from the following answers:  A) 5 hrs 22 min  B) 6 hrs 21 min  C) 7 hrs 14 min  D) 6 hrs  E) None of these

Solution: Explanation:   Time taken to travel 600 km = Distance/Speed =600/100= 
600/100 = 6
6 hour   Now we need to find out the number of stops in the 600 km travel.   Given that train stops after every 75 km.   600/75= 
600/75 = 8
8   It means train stops 7 times before 600 km and 1 time just after 600 km. Hence we need   to take only 7 stops into consideration for the 600 km travel.   Hence, total stopping time in the 600 km travel= 7 x 3 = 21 minutes   Total time needed to reach the destination = 6 hours + 21 minutes = 6 hrs 21 min   Answer: Option 6 hrs 21 min

Two Trains A and B start simultaneously from stations 500 miles apart, and travel the same route toward each other on adjacent parallel tracks. If Train A and Train B travel at a constant rate of 50 miles per hour and 50 miles per hour, respectively, how many miles will Train A have traveled when the trains pass each other, to the nearest mile? Choices: A) 112 B) 133 C) 150 D) 250 E) 288

Solution: Since we know the distance (500) and the combined rate (100), we plug it into the formula:   Distance = Rate * Time   500 = 100 * Time   We can solve for the time they will meet cause we added the rate of Train A and Train B together.   So the time will be 500/100 from dividing 100 on both sides to isolate Time in the equation above.   Time will be 5 hours so now you can plug that in for Train A’s distance.   250istance = Rate * Time   250istance = 50 * 5   250istance = 250 according to answer choice 250.

John started driving on a highway at a constant speed of R miles per hour at 13:00. Then, 2 hours later, Tom started driving on the same highway at a constant speed of 6R/5 miles per hour at 15:00. If both drivers maintained their speed, how many miles had John driven on the highway when Tom caught up with John?  Pick
A) 6R  B) 8R  C) 9R  D) 10R  E) 12R

Solution: In 2 hours, John drove 2R miles.   Tom can catch John at a rate of 6R/5 - R = R/5 miles per hour.   The time it takes Tom to catch John is 2R / (R/5) = 10 hours.   In 10 hours, John can drive another 10R miles for a total of 12R miles.   The answer is 12R.

Alex deposited x dollars into a new account that earned 5 percent annual interest, compounded annually. One year later Alex deposited an additional x dollars into the account. If there were no other transactions and if the account contained w dollars at the end of two years, which of the following expresses x in terms of w ?	Choose the correct option:	A) w/(1+1.08)	B) w/(1.05+1.05^2)	C) w/(1.16+1.24)	D) w/(1.08+1.16)	E) w/(1.08^2+1.08^2)

Solution: Account at the end of the first year would be 1.05x dollars. At this time x dollars was deposited, hence the account at the beginning of the second year would be (1.05x+x) dollars. Account at the end of the second year would be (1.05x+x)*1.05=w --> x(1.05^2+1.05)=w --> x=w/(1.05+1.05^2).   Answer: w/(1.05+1.05^2)

A rainstorm increased the amount of water stored in State J reservoirs from 50 billion gallons to 75 billion gallons. If the storm increased the amount of water in the reservoirs to 37.5 percent of total capacity, approximately how many billion gallons of water were the reservoirs short of total capacity prior to the storm?  Choose the correct choice from the following choices:
A) 90  B) 114  C) 124  D) 120  E) 127

Solution: After the reservoir is filled to 75 gallons the amount of water is at 37.5% - which means that 62.5% of the reservoir is empty. To figure out what that 62.5% is approximate: 75 gallons /37.5 percent = x gallons /62.5 percent , therefore, x = 125 gallons , answer choices A,B,C,D are below 125 . We know that the reservoir must be short more than 125 gallons, therefore, the only possible choice is 127.
