Question: The average age of 8 men is increased by 2 years. When two of them, whose ages are 20 years and 24 years respectively are replaced by two women. What is the average age of these women?
A.36 years
B.30 years
C.40 years
D.42 years
Answer: B.30 years
Explanation: Let the average age of 8 men be X years
Thus, Sum of the ages of 8 men = 8X years
Now, according to the condition of the question, average age of (6 men + 2 women) = (x + 2) years
Thus, Sum of the ages of (6 men + 2 women)
= 8(X + 2) = 8X x 16 years
Hence, it is clear that on replacing two men by two women, sum of their ages increased by 16 years.
Therefore, sum of the ages of two women
= (20 + 24) + 16 = 60 years
Thus, average age of the women = 60/2 = 30 years

Question: Students of three different classes appeared in common examination. Pass average of 10 students of first class was 50%, pass average of 15 students of second class was 60% and pass average of 25 students of third class was 80% then what will be the pass average of all students of three classes?
A.74%
B.75%
C.68%
D.72%
Answer: C.68%

= (50% of 10) + (60% of 15)+ (80% of 25)
= 5+9+20 = 34
Total students appeared,
= 10+15+25 = 50
Pass average,
= 34*100/50 = 68%.

Question: The value of ((x – y)³ + (y - z)³ + (z – x)³)/(8 (x – y) (y – z) (z – x))
is equal to :
A.0
B.1/12
C.3/8
D.1/4
Answer: C.3/8
Explanation: Since (x – y) + (y – z) + (z – x) = 0,
so (x – y)³ + (y – z)³ + (z – x)³= 3 (x – y) (y – z) (z – x).
(3 (x – y) (y – z) (z – x))/(8(x – y) (y – z) (z – x)) = 3/8.

Question: A committee of three students has to be formed. There are four candidates: Jane, Joan, Paul, Stuart, and Jessica. If Paul and Stuart refuse to be in the committee together and Jane refuses to be in the committee without Paul, how many committees are possible?
A.3
B.4
C.5
D.6
Answer: A.3
Explanation: Let's try a different problem with your approach. There are five people: A, B, C, D, E. Need to chose 3 for a committee. A and B cannot be chosen together. B and C cannot be chosen together. How many options?
Your approach: total 10 options, 5c3.
Now, assume the wrong scenario where A and B are chosen together. There are three such scenarios. (A and B are chosen, just need one more person.) So we have to subtract the three wrong options. Similarly, there are three wrong scenarios where B and C are chosen together.
This gives us 10-3-3=4 as the answer.
Yet this answer is wrong. There are five possibilities: ACD, ACE, ADE

Question: A train ,120 meters long travels at a speed of 45 km/hr crosses a bridge in 30 seconds. The length of the bridge is
A.270 m
B.255 m
C.235 m
D.220 m
Answer: B.255 m
Explanation: Explanation:
Assume the length of the bridge = x meter
Total distance covered = 120+x meter
total time taken = 30s
speed = Total distance covered /total time taken = (120+x)/30 m/s
=> 45 Ã— (10/36) = (120+x)/30
=> 45 Ã— 10 Ã— 30 /36 = 120+x
=> 45 Ã— 10 Ã— 10 / 12 = 120+x
=> 15 Ã— 10 Ã— 10 / 4 = 120+x
=> 15 Ã— 25 = 120+x = 375
=> x = 375-120 =255

Question: On a certain day, Tim invested $500 at 10 percent annual interest, compounded annually, and Lana invested 1,000 at 5 percent annual interest, compounded annually.The total amount of interest earned by Tim’s investment in the first 2 years was how much greater than the total amount of interest earned by Lana’s investment in the first 2 years?
A.$2.5
B.$15
C.$50
D.$100
Answer: A.$2.5
Explanation: Compounded annually means that the interest is applied once per year. One can have 10% annual interest compounded monthly - in this case 10%/12 would be applied each month, or 10% annual interest compounded daily etc.
With respect to the problem at hand, at the end of two years, Tim would have
500(1.10)^2 = 500(1.21) = 605
and Lana would have
1,000(1.05)^2 = 1,000(1.1025) =1102.5
Thus, Tim earned 105 dollars, while Lana earned 102.5 dollars
The difference is $2.5 and the answer is A.
Question: A train having a length of 1/4 mile , is traveling at a speed of 75 mph. It enters a tunnel 3 ½ miles long. How long does it take the train to pass through the tunnel from the moment the front enters to the moment the rear emerges?
A.3 min
B.4.2 min
C.3.4 min
D.5.5 min
Answer: A.3 min
Explanation: Explanation:
Total distance = 3 ½ + ¼ = 7/2 + ¼ = 15/4 miles
Speed = 75 mph
Time = distance/speed = (15/4) / 75 hr = 1/20 hr = 60/20 minutes = 3 minutes

Question: The ratio of the present age of Sandy to that of Molly is 7:2. Twelve years from now, the ratio of the ages of Sandy to Molly will be 5:2. What was Sandy's age 6 years ago?
A.39
B.45
C.51
D.57

Question: A customer using a certain telephone calling plan pays a fee of $25 per month, and then receives a discount of 40% on the regular charge for all calls made to country X. If calls to country X are regularly charged at $1.60 per minute for the first 3 minutes, and $0.80 per minute for each minute thereafter, what is the maximum the customer could have saved over regular prices if he was charged for 1 hour of calls made to country X in a certain month?
A.$8.75
B.$12
C.$13.40
D.$17.40
Answer: C.$13.40
Explanation: Discount = 40% of spending
We want to maximise discount so we will need to maximise spending. We do that by assuming that 60 calls were made of 1 min each because the first minute is the most expensive.
Max discount = (40/100)* 60 * 1.6 = (40/100)*96
This would be slightly less than 40. About 38 to 39.
Saving = (Slightly less than 40) - 25 = Slightly less than 15 charged in X country

Question: Nails and screws are manufactured at a uniform weight per nail and a uniform weight per screw. If the total weight of one screw and one nail is half that of 6 screws and one nail, then the total weight of 3 screws, and 3 nails is how many times that of 5 screws and 1 nails?
A.a. 4
B.b. 5/2
C.c. 2

Question: A mixture of 70 litres of milk and water contains 10% water. How many litres of water should be added to the mixture so that the mixture contains 12 1/2% water?
A.2 litres
B.3 litres
C.5 litres
D.7 litres
Answer: A.2 litres
Explanation: Quantity of milk in the mixture = 90/100 (70) = 63 litres.
After adding water, milk would form 87 1/2% of the mixture.
Hence, if quantity of mixture after adding x liters of water,
(87 1/2) / 100 x = 63 => x = 72
Hence 72 - 70 = 2 litres of water must be added.

Question: Paul sells encyclopedias door-to-door. He earns $40 on every paycheck, regardless of how many sets he sells. In addition, he earns commission as follows:
Commission Sales
10% $0.00 - $10,000.00
5% $10,000.01 --->
He does not earn double commission.That is, if his sales are $12,000, he earns 10% on the first $10,000 and 5% on the remaining $2,000.
His largest paycheck of the year was $1,320. What were his sales for that pay period?
A.13,200
B.14,800
C.14,900
D.15,600
Answer: D.15,600
Explanation: His pay check was $1320.
Out of this, $40 was his fixed salary so the total commission he earned was $1320 - $40 = $1280
He earns 10% on the sales of first $10,000 which gives a commission of $1000.
He earns 5% on every subsequent dollar. Since he earns another $280, he must have had sales of another 280*(100/5) = 5600
So his total sales must have been $10,000 + $5600 = $15,600

Question: A bag contains 2 yellow, 3 green and 2 blue balls. Two balls are drawn at random. What is the probability that none of the balls drawn is blue?
A.1/2
B.10/21
C.9/11
D.7/11
Answer: B.10/21
Explanation: Total number of balls = 2 + 3 + 2 = 7
Let S be the sample space.
n(S) = Total number of ways of drawing 2 balls out of 7 = 7C2
Let E = Event of drawing 2 balls , none of them is blue.
n(E) = Number of ways of drawing 2 balls , none of them is blue
= Number of ways of drawing 2 balls from the total 5 (=7-2) balls = 5C2
(∵ There are two blue balls in the total 7 balls. Total number of non-blue balls = 7 - 2 = 5)
P(E) = n(E)/n(S)=5C2/7C2=(5×4/2×1)/(7×6/2×1)=5×4/7×6=10/21
ANSWER:B
Question: there are 5 envelope and 5 letters placed at random. what is the probability that no single letter is placed in the right envelope
A.117/120
B.118/120
C.119/120
D.116/120
Answer: C.119/120
Explanation: probability that no single letter is placed in the right envelop is = 1- (placing all the letters in the right envelop)
i.e 5 letters will go in their right envelops in only 1 way, and total cases is 5!
so, 1-(1/5!) = 119/120

Question: Of the 120 passengers on Flight 750, 60% are female. 10% of the passengers sit in first class, and the rest of the passengers sit in coach class. If 1/3 of the passengers in first class are male, how many females are there in coach class?
A.44
B.48
C.50
D.64
Answer: D.64
Explanation: Number of passengers on flight = 120
Number of female passengers= .6*120 = 72
Number of passengers in first class = (10/100)* 120 = 12
Number of passengers in coach class = (90/100)* 120 = 108
Number of male passengers in first class = 1/3 * 12 = 4
Number of female passengers in first class = 12-4 = 8
Number of female passengers in coach class = 72 - 8 = 64
