1. In a classroom the average height of all the boys was 170 cm. Rahim recently joined the class which originally had 20 boys increased the average to 171cm. Then find the height of Rahim.
A. 185 cms
B. 191 cms
C. 190 cms
Before Rahim joined the total height of all the boys = 170 X 20 = 3400.
New average = (Total height of all students + height of Rahim)/21 = 180
Therefore (3400 + height of Rahim)/21 = 171
Therefore height of Rahim = 3780 - 3400 = 191 cms.
2. The average age of a group of 12 students is 20years. If 4 more students join the group, the average age increases by 1 year. The average age of the new students is
Total age of 12 students=12*20=240
Total age of 4 students =4x (assuming the average age of 4 students)
Hence the equation=240+4x=16*21=336
solving the equation we get x=24
So, average age of the new students =24.
3. The price of a jewel, after passing through three merchants rises on the whole by 80%. If the first and the second merchants earned 20% and 25% profit respectively, find the percentage profit earned by the third merchant.

120 ----- +25%----150
4. A constructor estimates that 3 people can paint Mr. khans house in 4 days. If he uses 4 people instead of 3, how long will they take to complete the job?
Given, 3 people requires 4 days.
As the people are increased to 4, i.e. 3*(4/3) =4, so work will be reduced to (3/4) *4=3 days.
5. How many 4-letter words with or without meaning, can be formed out of the letters of the word, 'LOGARITHMS', if repetition of letters is not allowed?
The Word LOGARITHMS is containing 10 letters.

6. If 6th March, 2005 is Monday, what was the day of the week on 6th March, 2004?
The year 2004 is a leap year. So, it has 2 odd days.
But, Feb 2004 not included because we are calculating from March 2004 to March 2005. So it has 1 odd day only.
The day on 6th March, 2005 will be 1 day beyond the day on 6th March, 2004.
Given that, 6th March, 2005 is Monday.
6th March, 2004 is Sunday (1 day before to 6th March, 2005).
7. At 6′o clock, a clock ticks 6 times. The time between first and last ticks is 30 seconds. How long does it tick at 12′o clock?
A. 66 secs
B. 55 secs
C. 60 secs
D. 62 secs
For ticking 6 times, there are 5 intervals.
Each interval has time duration of 30/5=6 secs.
At 12 o'clock, there are 11 intervals.
So total time for 11 intervals = 11*6=66 secs.
8. Two urns contain respectively 2 red 3 white and 3 red,5 white balls. One ball is drawn at random from the first urn and transferred into the second. A ball is now drawn from the second urn and it turns out to be red. What is the probability that the transferred ball was white?
According to the Baye's theorem,
p (no of way to drawn a ball from 2nd urns is red and ball transferred from 1 urns) =(3c1/5c1) *(3c1/9c1) =9/45.
Total=(2c1/5c1) *(4c1/9c1) +(3c1/5c1) *(3c1/9c1) =17/45.
So, probability = (9/45)/ (17/45) = 9/17.
9. Two trains A and B start simultaneously from stations X and Y towards each other respectively. After meeting at a
point between X and Y, train A reaches station Y in 9 hours and train B reaches station X in 4 hours from the
time they have met each other. If the speed of train A is 36 km/hr., what is the speed of train B?
A. 24 km/hr.
B. 54 km/hr.
C. 81 km/hr.
D. 16 km/hr.
The total distance between X & Y is 9*36 km.
Therefore, the speed of B = (9*36)/4 = 81 kmph.
10. An alloy of zinc and copper contains the metals in the ratio 5: 3. The quantity of zinc to be added to 6 kg of the alloy so that the ratio of the metal may be 3: 1 is:
A. 5 kg
B. 2 kg
C. 3 kg
D. 4 kg
In 6kg of alloy 15/4-zinc and 9/4-copper.
So, let extra zinc added be x.
=> (15/4+x)/ (9/4) =3/1.

Since, 2+1+5+ 4+7+4 =23
Therefore, 5+3+7+x = 23.
=> x = 8.
Combination that match 8 is 26 since 2+6=8.
13. If in a coded language, 2+6+7=24, 8+2+8=73, 3+4+4=40.
As we have
Now Consider no.9 then 29 then 55 then 87
Its series of difference 29 and 9 as 5×4+0=20
Then 55 and 29 as 5×5+1=26.
Then 87 and 55 as 5×6+2=32.
14. Pointing towards a photo on wall Raju said "His father’s only granddaughter is my wife" how Raju is related to that man in photo.

At this stage of civilization, when many nations are brought in to close and vital contact for good and evil, it is essential, as never before, that their gross ignorance of one another should be diminished, that they should begin to understand a little of one another's historical experience and resulting mentality. It is the fault of the English to expect the people of other countries to react as they do, to political and international situations. Our genuine goodwill and good intentions are often brought to nothing, because we expect other people to be like us. This would be corrected if we knew the history, not necessarily in detail but in broad outlines, of the social and political conditions which have given to each nation its present character.
