Question: Three coworkers P , W , R meet for Dinner. P had 5 sandwiches, W had 3 and R had none. Both PW share their sandwiches with R such that each one got the same amount. If R paid $ 8 to PW, how much of $ 8 should P get? Assume both sandwiches and Dollars can be split.
A.a) 5$
B.b) 3 $
C.c) 7 $
D.d) 4 $
Answer: C.c) 7 $
Explanation: we got total 8 sandwiches ....we are dividing equally in 3 people.
per person: 8/3
initially
p:8
W:3
r:0
now since r ate 8/3 so he is paying 8 dollars for 8/3 sandwiches.
now p also ate 8/3 of his 5 sandwiches = so he gave 5-8/3 to r ==>7/3 to r
ok we have 8 dollars for 8/3 sandwich
therefore for 7/3 sandwich we will get 7 dollars.
hence p should get 7 dollars.
hence C
Question: A company’s four cars running 10 hrs a day consume 1200 lts of fuel in 10 days. In the next 6 days, the company will need to run 9 cars for 12 hrs each so it rents 5 more cars which consume 25% less fuel than the company’s four cars. How many lts of fuel will be consumed in the next 6 days?
A.1200 lt
B.1555 lt
C.1674 lt
D.1728 lt
Answer: C.1674 lt
Explanation: Given that
4 cars running 10 hrs a day consume 1200 lts. of fuel in 10 days.
1 car consumption per hour per day = 1200 /4 *10 *10 = 3 litre
Now question say new car consume 20% less fuel than the company’s four cars = 75/100 of 3 = 2.25 ( 25 percent less than 3)
Hence we calculate total consumption for next 6 days, the company will need to run 5 new cars for 12 hrs = 2.25 *12 *6*5 =810
similarly = old 4 car consumption for next 6 days for 12 hrs = 3*6*12*4 = 864
hence total is = 810+864 = 1674 lt

Question: For integers x, y, and z, if (3^x) (4^y) (5^z) = 52,428,800,000 and x + y + z = 17, what is the value of xy/z?
A.0
B.2
C.4
D.6
Answer: A.0
Explanation: The number 52,428,800,000 is not divisible by 3. (We can verify this by adding the digits of the number to see that the sum is not a multiple of 3.)
Thus x = 0 and xy/z = 0.
The answer is A.
Question: An urn contains 10 black and 5 white balls. Two balls are drawn from the urn one after the other
without replacement. What is the probability that both drawn balls are black?
A.1/2
B.1/5
C.1/5
D.3/7
Answer: D.3/7
Explanation: Let E and F denote respectively the events that first and second ball drawn
are black. We have to find P(E n F) or P (EF).
Now P(E) = P (black ball in first draw) = 10/15
Also given that the first ball drawn is black, i.e., event E has occurred, now there are 9 black balls and five white balls left in the urn. Therefore, the probability that the second ball drawn is black, given that the ball in the first draw is black, is nothing but the conditional probability of F given that E has occurred.
That is P(F|E) = 9/14
By multiplication rule of probability, we have
P (E n F) = P(E) P(F|E)
= 10/15 × 9/14 = 3/7

Question: The batting average of a particular batsman is 60 runs in 46 innings. If the difference in his highest and lowest score is 180 runs and his average excluding these two innings is 58 runs, find his highest score.
A.179
B.194
C.269
D.177
Answer: B.194
Explanation: Explanation:
Total runs scored by the batsman = 60*46 = 2760 runs
Now excluding the two innings the runs scored = 58*44 = 2552 runs
Hence the runs scored in the two innings = 2760 â€“ 2552 = 208 runs.
Let the highest score be x, hence the lowest score = x â€“ 180
x + (x - 180) = 208
2x = 388
x = 194 runs

Question: If money is invested at r percent interest, compounded annually, the amount of the investment will double in approximately 48/r years. If Pat's parents invested $5,000 in a long-term bond that pays 8 percent interest, compounded annually, what will be the approximate total amount of the investment 18 years later, when Pat is ready for college?
A. $20000
B. $15000
C. $12000
D. $10000
Answer: B. $15000
Explanation: Since investment doubles in 48/r years, then for r=8 it'll double in 48/8=~6 years (we are not asked about the exact amount so such an approximation will do). Thus after 18 years investment will become $5,000*3=$15,000 .

A.Rs 34
B.Rs 33
C.Rs 8
D.None of the above
Answer: A.Rs 34
Explanation: Explanation :
Let the person buy c chocolates, 2c buiscuits. Therefore, apples is >3c.
In any case, total cost will be
=>cost of chocolates + cost of biscuits + cost of apples.
=> (c*1) + [2c*0.5] + (2*something greater than 3c).
Thus, Total cost=>
=> 2c + (2* something greater than 3c).
Here, the total cost is an even number. Thus ans should be an even number.
Taking c=1, the total minimum cost we get is 10.
Thus the only other option that satisfies the constraints is 34.

Question: It is known that no more than 5 children will be attending a party. What is the smallest number of cookies that must be brought to the party so that each child receives the same number of cookies?
A.35
B.105
C.60
D.210
Answer: C.60
Explanation: The question states that there are no more than 5 children in the party. Thus, the possibility is that there could be 1, 2, 3, 4 or 5 children.
If you assume answer as 35 and there are 3 children, you may not distribute be able to distribute cookies equally.
similarly if there were 105 cookies, and 2 children, cookies cannot be distributed equally.
