David gets on the elevator at the 11th floor of a building and rides up at the rate of 57 floors per minute. At the same time, Albert gets on an elevator at the 51st floor of the same building and rides down at the rate of 63 floors per minute. If they continue travelling at these rates, then at which floor will their paths cross ?
19
28
30
37
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:

Suppose their paths cross after x minutes.

Then, 11 + 57x = 51 - 63x       120x = 40

x = 1
3

Number of floors covered by David in (1/3) min. = 1 x 57 = 19.
3

So, their paths cross at (11 +19) i.e., 30th floor.

Average age of employees working in a department is 30 years. In the next year, ten workers will retire. What will be the average age in the next year?

I. 

Retirement age is 60 years.

 II. 

There are 50 employees in the department.

I alone sufficient while II alone not sufficient to answer
II alone sufficient while I alone not sufficient to answer
Either I or II alone sufficient to answer
Both I and II are not sufficient to answer
Both I and II are necessary to answer
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:

 I. Retirement age is 60 years.

II. There are 50 employees in the department.

Average age of 50 employees = 30 years.

Total age of 50 employees = (50 x 30) years = 1500 years.

Number of employees next year = 40.

Total age of 40 employees next year (1500 + 40 - 60 x 10) = 940.

Average age next year = 940 years = 23 1 years.
40 2

Thus, I and II together give the answer. So, correct answer is (E).

The percentage profit earned by selling an article for Rs. 1920 is equal to the percentage loss incurred by selling the same article for Rs. 1280. At what price should the article be sold to make 25% profit?
Rs. 2000
Rs. 2200
Rs. 2400
Data inadequate
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:

Let C.P. be Rs. x.

Then, 1920 - x x 100 = x - 1280 x 100
x x

1920 - x = x - 1280

2x = 3200

x = 1600

Required S.P. = 125% of Rs. 1600 = Rs. 125 x 1600 = Rs 2000.

X and Y can do a piece of work in 20 days and 12 days respectively. X started the work alone and then after 4 days Y joined him till the completion of the work. How long did the work last?
6 days
10 days
15 days
20 days
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:

Work done by X in 4 days = 1 x 4 = 1 .
20 5

Remaining work = 1 - 1 = 4 .
5 5

(X + Y)'s 1 day's work = 1 + 1 = 8 = 2 .
20 12 60 15

Now, 2 work is done by X and Y in 1 day.
15

So, 4 work will be done by X and Y in 15 x 4 = 6 days.
5 2 5

Hence, total time taken = (6 + 4) days = 10 days.

In a flight of 600 km, an aircraft was slowed down due to bad weather. Its average speed for the trip was reduced by 200 km/hr and the time of flight increased by 30 minutes. The duration of the flight is:
1 hour
2 hours
3 hours
4 hours
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:

Then, 600 - 600 = 200
x x + (1/2)

600 - 1200 = 200
x 2x + 1

x(2x + 1) = 3

2x2 + x - 3 = 0

(2x + 3)(x - 1) = 0

x = 1 hr.      [neglecting the -ve value of x]

None of these
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:

  I. Material cost = Rs. 2.50 per m2

 II. Labour cost = Rs. 3500.

III. Total cost = Rs. 14,500.

Let the area be A sq. metres.

Material cost = Rs. (14500 - 3500) = Rs. 11,000.

5A = 11000     A = 11000 x 2 = 4400 m2.
2 5

Thus, all I, II and III are needed to get the answer.

Correct answer is (C).

A cistern of capacity 8000 litres measures externally 3.3 m by 2.6 m by 1.1 m and its walls are 5 cm thick. The thickness of the bottom is:
90 cm
1 dm
1 m
1.1 cm
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:

Let the thickness of the bottom be x cm.

Then, [(330 - 10) x (260 - 10) x (110 - x)] = 8000 x 1000

320 x 250 x (110 - x) = 8000 x 1000

(110 - x) = 8000 x 1000 = 100
320 x 250

x = 10 cm = 1 dm.

A man bought 20 shares of Rs. 50 at 5 discount, the rate of dividend being 13. The rate of interest obtained is:
12 1 %
2
13 1 %
2
15%
16 2 %
3
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:

Investment = Rs. [20 x (50 - 5)] = Rs. 900.

Face value = Rs. (50 x 20) = Rs. 1000.

Dividend = Rs. 27 x 1000 = Rs. 135.
2 100

Interest obtained = 135 x 100 % = 15%

In how many different ways can the letters of the word 'OPTICAL' be arranged so that the vowels always come together?
120
720
4320
2160
None of these
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:

The word 'OPTICAL' contains 7 different letters.

When the vowels OIA are always together, they can be supposed to form one letter.

Then, we have to arrange the letters PTCL (OIA).

Now, 5 letters can be arranged in 5! = 120 ways.

The vowels (OIA) can be arranged among themselves in 3! = 6 ways.

Required number of ways = (120 x 6) = 720.

10

The rate percent is:

11%
10%
5%

Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:

Let T.D. be Re. 1.

Then, B.D. = Rs. 11 = Rs. 1.10.
10

Sum = Rs. 1.10 x 1 = Rs. 110 = Rs. 11.
1.10 - 1 10

S.I. on Rs. 11 for 2 years is Rs. 1.10

Rate = 100 x 1.10 % = 5%.
