Q6. A man buys a land and gives for it 20 times the annual rent. Find the rate of interest he gets for his money.

A. 10%
B. 24%
C. 45%
D. 18%
E. 5%

ANS: E

Explanation:

let annual rent is 1 Rs. so buys the land at 20 Rs. So by investing Rs.20 he is getting Rs.1 as interest. so on Rs.100 he gets Rs.5 . so rate%=5%.Hence option E is the answer.

Q7. A circle has two parallel chords of lengths 6 cm and 8 cm. If the chords are 1 cm apart and the centre is on the same side of the chords, then the diameter of the circle is of length:

A. 5 cm
B. 6 cm
C. 10 cm
D. 12 cm

ANS: C

Explanation:

In the given figure, EB = 3 cm, FD = 4 cm, EF = 1 cm
Let OF = a cm
In triangle OFD, r2 = a2 + 42     &   in triangle OEB, r2 = (a+1)2 + 32
Solving the above two equations, we get a = 3cm
Putting the value of a in any of the above equation, we get r = 5 cm
Therefore, diameter = 10 cm

Q8. In how many different ways can the letters of the word PARTY be arranged?

A. 120
B. 2005

D. 720
E. None of these

Q9. A basket contains 3 blue, 5 black and 3 red balls. If two balls are drawn at random, what is the probability that none of them is blue?

A. 22/55
B. 3/55
C. 28/55
D. 9/11
E. None of these

ANS: C

Explanation:

Q10. Ramesh takes twice as much time as Mahesh and thrice as much time as Suresh to complete a job. If working together, they can complete the job in 4 days, then the time taken by each of them separately to complete the work is

A. 36, 24 and 16 days
B. 20, 16 and 12 days
C. 24, 12 and 8 days
D. None of these

ANS: C

Explanation:

We are given that R = 2M = 3S. This means that Suresh is thrice efficient than Ramesh and Mahesh  is twice efficient than Ramesh. So let us assume that Ramesh can do 1 unit work per day. so Mahesh will do 2 units per day and Suresh will do 3 units of the work per day. So the total work done by all three in one day is 6 units. Now they together take 4 days to complete the work. So the total work is 6 x 4 = 24 units and individually Ramesh, Mahesh and Suresh will take 24 days, 12 days and 8 days respectively.

Q11. A basket contains 3 blue, 5 black and 3 red balls. If 2 balls are drawn at random, what is the probability that one is black and one is red?

A. 2/11
B. 8/11
C. 9/11
D. 3/11
E. None of these

ANS: D

Explanation:

Selecting 1 black ball out of 5 - 5C1 ways Selecting on red ball out of 3 - 3C1 ways The required probability =

Q12. In a rhombus ABCD the diagonals AC and BD intersect at the point (3, 4). If the point A is (1, 2), the diagonal BD has the equation

A. x - y - 1 = 0
B. x - y + 1 = 0
C. x + y - 1 = 0
D. x + y - 7 = 0

ANS: D

Explanation:

Slope of AC = (2-4)/(1-3) = 1. As diagonals in a rhombus bisect each other at 90Â°, so slope of BD = -1. Also diagonal BD has to lie on the point (3, 4), so equation of the line is y - 4 = - 1(x - 3) => x + y â€“ 7 = 0.

Q13. What will be the compound interest on a sum of Rs. 7200/- at 5 p.c.p.a. in 2 years?

A. Rs. 841/-
B. Rs. 738/-
C. Rs. 793/-
D. Rs. 812/-
E. Rs.694/-

ANS: B

Explanation:

Q14. A & B together can complete a piece of work in 16 days, B alone can complete the same work in 24 days. In how many days can A alone complete the same work?

A. 34 days
B. 50 days
C. 48 days
D. 42 days
E. None of these

ANS: C

Explanation:

Let A alone can complete the work in x days and B alone can complete the work in 24days. Therefore, according to the given conditions, 1/x + 1/24 = 1/16 1/x = 1/48 So, As one day work is 1/48 which means that A will complete the entire work in 48days.
Therefore, the answer is option C.

Q15. An express train travelled at an average speed of 100 kmph, stopping for 3 minutes after every 75 km. A local train travelled at a speed of 50 kmph, stopping for 1 minute after every 25 km. If the trains began travelling at the same time, how many kilometres did the local train travel in the time it took the express train to travel 600 km?

A. 900 km
B. 307.5 km
C. 1200 km
D. 100 km

ANS:

Explanation:

For 600 kms. The Express train needs 6 hrs. for the distance travelled @ 100 kmph and it will stop for ( 600/75 )= 8. So there must be 7 stoppages in between where it stops for 3 min. each totalling upto 21 min. So total time will be 6 hrs.21 min.

Now the Local train travelling @ 50 kmph will cover 300 kms. in 6 hrs and in rest 9 min. it will travel 7.5 kms.( 300/25=12 stoppages where it will stop for 12 min. So, 21- 12 = 9 ). The total distance becomes 300 + 7.5 = 307.5 km.

ALTERNATE SOLUTION:

We can also think that since speed of express train is double the local speed, so local train will travel less than 600 km, Only option b has such option and hence is the required answer.

DIRECTIONS for questions 36 to 40:  Read the given passage and answer the questions.

Why do the vital organs of the body slow down on aging? Why do older people experience sleep disorders? A new study holds the molecular machinery of the master clock in the brain responsible for such malfunctions during old age. The study conducted by researchers at the University of Virginia and reported in the journal Proceedings of the National Academy of Sciences, compares the working of the vital organs to a wall full of clocks with a large dominant clock controlling the synchronization of the peripheral clocks.

The big clock continues to keep time, but as it ages, its connecting signal to the smaller docks weakens. Some of the smaller clocks eventually become desynchronized and some stop running. This weakening of the signal, rather than a problem with the central timekeeper itself, apparently is the cause of alterations in the biological timing system in aging mammals - possibly including humans, according to the researchers.

This may explain why older people experience sleep disorders the signal from the master clock in the brain has weakened, even as it keeps on ticking. This weakened output causes some of the peripheral clocks in other organs to eventually stop oscillating or to fall out of proper sync, causing sleep disruption and malaise, the report says. Lack of sleep can affect more than a persons level of alertness. In the long term, it can disrupt the bodys metabolism; affect eating cycles, lead to declining cognitive abilities and possibly, a shortened lifespan. Sleep disorders are also associated with Alzheimers disease.

Gene D. Block, professor of biology and one of the studys lead researchers, was quoted in the report as saying, Our new finding demonstrates that the molecular machinery of the master clock continues to function normally. Taken together with our earlier studies, this suggests that there may be an age-related failure of the conversion of the clocks molecular rhythm into the electrical or humeral signals that the brain uses for communication. These weakened central signals may fail to keep some peripheral clocks appropriately synchronized or, in some cases, even rhythmic.

The scientists studied tissues from the brain and other organs of older mice and measured the activity of a gene that is a part of the biological clock. They found that the central dock in the brain, the supra chiasmatic nucleus, maintained proper periodicity and synchronization. Clocks in some peripheral organs, such as the liver and kidney of older animals, were either improperly synchronized or had lost rhythm entirely. This new knowledge could eventually lead to new therapies for age-related desynchronization, Block said. Arrhythmic or improperly synchronized tissues of old animals could possibly be stimulated by a treatment to oscillate normally.

Q36. What was the breakthrough achieved, as a result of the scientists effort?

A. The discovery of the fact that the clocks in some peripheral organs were either improperly synchronized or had lost their rhythm completely
B. The observation that the brain uses humeral signals for communication
C. The knowledge that the oscillation is necessary to maintain a persons level of alertness
D. None of these

ANS: A

Q37. Which of the following sentences is incorrect, according to the passage?

A. There is a similarity in the functioning of the brain and the vital organs of the human body with that of a wall full of clocks and the big clock synchronizing them
B. The study of tissues from the brain and other organs of mice helped scientists discover that even though the supra chiasmatic nucleus maintained time properly, the clocks in the peripheral organs were either out of sync or had lost rhythm entirely.
C. The molecular machinery of the brain is responsible for the entire malfunctioning occurring at older ages
D. None of these

ANS: C

Q38. Which of these factors is held responsible for the slowing down of the vital organs in old age as laid down in the passage?

A. Molecular machinery of the master clock and the peripheral clocks in the brain
B. Weakening of the signals from the master clock in the brain

D. Sleep disorders
