Question: Due to an increase in 30% in the price of eggs, 3 eggs less are available for Rs. 7.80. Find the present rate of eggs per dozen.
Options:
A)Rs. 8.36
B)Rs. 9.36
C)Rs. 10.36
D)Rs. 11.36
E)Rs. 11.98
Rationale: Let the original price per egg be Rs x
Then increased price will be,
(130/100 x)
=7.80/x −7.80/(130/100) x =3
=7.80/x −780/130x =3
=390x=234
x=0.6
Actual price was Rs 0.6
Present price per dozen will be
Rs.(12∗130/100 ∗0.6)=Rs.9.36

If the cards are counted 4 at a time , there is 1 left over
x= 4q+1
x can take values 501 , 506
Therefore , x = 506

Question: If a truck is traveling at a constant rate of 54 kilometers per hour, how many seconds will it take the truck to travel a distance of 600 meters? (1 kilometer = 1000 meters)
Options:
A)18
B)24
C)30
D)36
E)40
Rationale: Speed = 54 Km/hr => 54,000 m/hr
In one minute => 54000/60 = 900 meters
In one sec => 900/60 = 15 meters
Time = Total distance need to be covered / Avg. speed
=> 600/ 15 =40 and hence the Answer : E

Question: For all even integers n, h(n) is defined to be the sum of the even integers between 4 and n, inclusive. What is the value of h(18)/h(10) ?
Options:
A) 3
B) 1.8
C) 6
D) 18
E) 60
Rationale: CONCEPT: When terms are in Arithmetic Progression (A.P.) i.e. terms are equally spaced then
Mean = Median =(First+Last)/2
and Sum = Mean*Number of terms
h(18) = [(4+18)/2]*8 = 88
h(10) = (4+10)/2]*4 = 28
h(18)/h(10) = (88) / (28) ~ 3

Options:
A)630
B)700
C)535
D)450
E)815

Question: When running a mile during a recent track meet, Nuria was initially credited with a final time of 3 minutes, 44 seconds. Shortly after her run, officials realized that the timing mechanism malfunctioned. The stopwatch did not begin timing her until 11/25 of a minute after she began to run. If the time was otherwise correct, how long did it actually take Nuria to run the mile?
Options:
A)5 minutes, 17.6 seconds
B)5 minutes, 21.8 seconds
C)4 minutes, 10.4 seconds
D)5 minutes, 44.44 seconds
E)5 minutes, 43.56 seconds
Rationale: One approach:
The watch starts to work after Nuria began his running. It means the time should be greater than credited 3 minutes, 44 seconds. The only number is 4 minutes, 10.4 seconds.
Another approach:
11/25 close to 30 second when added to the 3 minutes, 44 seconds, it means it passes 4 minute.

Question: Mrs. Rodger got a weekly raise of $147. If she gets paid every other week, write an integer describing how the raise will affect her paycheck.
Options:
A)$140
B)$141
C)$142
D)$147
E)$145
Rationale: Let the 1st paycheck be x (integer).

= $ (x + 147 + 147)
= $ (x + 294)
So in this way end of every week her salary will increase by $ 147.

Question: At an upscale fast-food restaurant, Shin can buy 3 burgers, 7 shakes, and one cola for $120. At the same place it would cost $160.50 for 4 burgers, 10 shakes, and one cola. How much would it cost for a meal of one burger, one shake, and one cola?
Options:
A)$21
B)$27
C)$31
D)$39
E)It cannot be determined
Rationale: let's suppose that the price of a burger is BB, of a shake - SS and that of a cola is CC. We can then construct these equations:
3B+7S+C=120
4B+10S+C=160.5
Subtracting the first equation from the second gives us B+3S=40.5
Now if we subtract the new equation two times from first or 3 times from second we will get B+S+C=39. In any case, there is no necessity to know each item's price, just the sum.

Question: A sum of Rs. 725 is lent in the beginning of a year at a certain rate of interest. After 8 months, a sum of Rs. 362.50 more is lent but at the rate twice the former. At the end of the year, Rs. 33.50 is earned as interest from both the loans. What was the original rate of interest?
Options:
A)3.6%
B)4.5%
C)5%
D)6%
E)None of these
Rationale: (725 x R x 1 /100) + (362.50 x 2R x 1 /100 x 3 ) = 33.50
(725 x 1 /100 + 362.50 x 2 /100 x 3) R = 33.50
(725 x 3 + 725 / 100 x 3) R = 33.50
(2175 + 725 ) R = 33.50 x 100 x 3
(2900) R = 10050
R = 10050/2900
R = 3.46%

Question: If a = (1/5)b and c = 9a, then which of the following represents the average (arithmetic mean) of a, b, and c, in terms of a ?
Options:
A) a + 4
B) (11/3)a
C) 4a
D) 5a
E) (7 1/4)a
Rationale: Official Answer: D
The average of the three variables isa + b + c/3. However, we need to solve in terms of a, which means we must convert b and c into something in terms of a.
Were told that a =1/5b, which is equivalent to b = 5a. We can plug that in and simplify the average to:a + 5a + c/3
We also know that c = 9a, which we can plug directly into the average expression:
a + 5a + 9a/3
= 15a/3 = 5a, choiceD.

A) a profit of $10
B) a profit of $8
C) a loss of $8
D) a loss of $20
E) neither a profit nor a loss
Rationale: $ Profit of the share sold at 20% profit =
120-90
20-?
$10 profit on the sale of 1 share.
$ Loss of the share sold at 20% loss=
80-90
20-?
$30 loss on the sale of 1 share.
10-30=Loss of $20

Question: Machine Z takes 2 more hours than machine B to make 20 widgets. If working together, the machines can make 25 widgets in 3 hours, how long will it take machine Z to make 40 widgets?
Options:
A) 5
B) 6
C) 8
D) 10
E) 12
Rationale: i approached this one by plugging in numbers...started with C.
if 40 are made in 8 hours, then 20 are made in 4 hours. so time of Z is 4, and time of B is 2.
rate together: 20/4 + 20/2 = 5+10 = 15. so in 1 hour, together make 15 widgets. in 3 hours = 45. way too much. we can eliminate right away C, B, and A - because B and A reduces the time - the total # of widgets made will be even higher.
now between D and E -> try only one ..if it doesn't work, then the other one is the answer.
i picked E:
12h to make 40 widgets, and 6 hours to make 20. this is the time of Z. time of B=4 hours.
20/6 + 20/4 = 10/3 + 20/4
find LCM of 3 and 4 = 12. multiply first by 4, and second by 3:
40+60/12 = 100/12
divide by 4:
25/3
so this is the rate given.
E is the correct answer
Answer: E

Question: A certain deck of cards contains 2 blue cards, 2 red cards, 2 yellow cards, and 2 green cards. If two cards are randomly drawn from the deck, what is the probability that they will both be not red?
Options:
A)15/28
B)1/4
C)9/16
D)1/32
E)1/16
Rationale: The question asks they will both be not red. Considering that these are draws without replacement there are following possibilities :
draw 1, draw 2
===== =====
1) Not Red, Red;
2) Red, Not Red;
3) Red, Red;
4) Not Red, not Red;
The answer has to be either P(4) OR all exclusion of the 3 previous conditions i.e. 1- [P(1) + P(2) + P(3)] => neither of the draws are Red
P(4) = 6/8*5/7=15/28
1- [P(1) + P(2) + P(3)] = 1 - [ (6/8 * 2/7) + (2/8*6/7) + (2/8*1/7)] = 1 - [26/8*7] = 1 - [13/28] = 15/28

Question: Two bus tickets from city A to B and three tickets from city A to C cost Rs. 462 but three tickets from city A to B and two tickets from city A to C cost Rs. 438. What are the fares for cities B and C from A ?
Options:
A)s. 4, Rs. 23
B)s. 13, Rs. 17
C)s. 15, Rs. 14
D)s. 77, Rs. 103
E)s. 78, Rs. 102
Rationale: If fares for cities B and C from A are x and y respectively, then
2x+3y=462 or 6x+9y= 1386
3x+2y =438 or 6x+4y= 876
subtracting
5y = 510
y= Rs 102
Hence e. Rs. 78, Rs. 102

He selling at 3.5 a rupee, his SP = 4
Profit = SP - CP = 4 - 3.5 = 0.5
Profit Percent = 0.5/3.5 * 100 = 14.28 %

Rationale: Total # of ways to distribute SSEGT among 5 sisters (without restriction) is 5!2!=605!2!=60;
The # of ways when the youngest niece gets G is: 4!2!=124!2!=12 (give G to youngest and then distribute SSET among 4 sisters).
So, # of ways when youngest niece doesn't get G is: 60−12=4860−12=48.
Answer: 48.
