pole
A pole seen from a certain distance at an angle of 15deg and 100m ahead by 30deg.what is the height of pole?

Let the height of the pole be hlet the distance at which the angle of elevation is 30 be x.then we havetan 15 is h/100+xtan 30 is h/xby solving we get x as 866and the height as 499.7 which is approx 500m

The height of the pole is 50 mappllying trigo, we get,.tan 15 = h/(100+y) ;tan 30 = h/y;solving above, we geth=50m

one angle of the triangle is 3 times a second angle and third angle is 20degrees more than the second angle. Then the second angle is?

First step:let the second angle be:xTherefore the first angle:3xand third angle becomes:x+20Therefore ATQX+3X+X+20=180(As the three side of the angle total is 180)5x=160x=32so,The second angle is 32

If the product of the 3 consecutive integers is 210, then the sum of the two smaller integers?
madhurimasridhar
- Mar 5th, 2009
Product is 210... so one of the integers must be 5 or 10.They are 5 6 7 or 3 4 5 or 10 9 8 or 10 11 12
Possible ans is 5 6 7 bcoz no other option gives the product which is mentioned
in the data.Sum of two smaller integers is 5+6=11.so ans is 11chandradeepika
- May 27th, 2008
the three consecutive integers be x,y and z.given: xyz=210. the unit place ends with 0. so it must be a multiple of 5,10,...if it is a multiple of 10 means it must lead to a large number because 10*9*...

As we have n=2, thus control goes to case2: thus,value of sum becomes 3 and since there is no break stmt thus,sum is again found as (2*3)=6.Thus the value of sum is 6.

The answer is very klear,as As the loop says when d expression1 is true it continues and then goes into the while condition to see dat if the expression 2 is true then only the loop continues,else breaks off from the loop when the expression2 goes false.

There are 5 distinct pairs of white socks and 5 pairs of black socks in a cupboard. In the dark, how many sock22s do I have to pull out to ensure that I have at least 1 correct pair of white socks?
vaidhyanathan
- Oct 31st, 2008
The worst possible case arises when The first 10 pull results in 10 black socks and the next 5 pull results in 5 white socks which do not have their exact pair.so after pulling the 16th sock, definitely there would be atleast 1 correct pair of white socks.hence the ans is 16 socks.

Consider the follwoing IF condition:IF A LESS 1200 IF B GREATER 25 MOVE 47 TOC ELSE MOVE 57 TO C IF A GREATER 249 MOVE 67 TO C ELSE NEXT SENTENCE ELSE IF B LESS 67 MOVE 27 TO C What will be the value of C, when A is 137 and b is 25 (a) 27 (b) 57 (c) 67(d) none
thequestsailor
- Jun 25th, 2007
The answer is a. 27in the first if else statement the condition fulfills and it will move 57 to C and then gradually going to the 2nd loop the condition again fulfills and then it will replace the previously stored 57 and replace it by 27 as per the condition of the 2nd loop.

There is a file whose ORGANISATION is INDEXED.you want to read the records from the file in RANDOM fashion as well as sequentially. Then which of the access mode would you specify? a.SEQUENTIAL b.RANDOM c.DYNAMIC d .ACCESS MODE has nothing to do with it
jassi
- Oct 4th, 2007
Answer is we will go for Dynamic Access Mode. Because dynamic will first start from the record like random access then it will go for sequential access in file. So random and sequential both are done.

Confucius said that to know the future we have to understand the past his time transport ,communications and scientific knowledge were less developed than they are today. News took weeks to travel where as today satellite links connect the continents virtually instantaneously. But our technological advances in the field of communications seem not to have improved our capacity to understand one another.
in Confucius day people were more intelligent (True/False/Can't say)We understand each other better now than in Confucius time because we can travel more quickly (True/False/Can't say)We have made great improvements in transport since Confucius day (True/False/Can't say)None of our scientific discoveries has really improved our lives (True/False/Can't say)

In the past helicopters are forced to ground or crash because of the formation of the ice on the rotors and engines. A new electronic device has been developed which can detect the water content in the atmosphere and warns the pilot if the temperature is below freezing temp about the formation of the ice on the rotors and wings.
the electronic device can avoid formation of the ice on the wings (True/False/Can't Say)There will be the malfunction of rotor & engine because of formation of ice (True/False/Can't Say)The helicopters are to be crashed or down (True/False/Can't Say)There is only one device that warn about the formation of ice (True/False/Can't Say)

Copernicus is the intelligent. In the days of Copernicus the transport and technology development was less & it took place weeks to communicate a message at that time. Where in we can send it through satellite with in no time. Even with these fast developments it has become difficult to understand each other.

A bus cover 27miles with 18mph in=27/18 =1hr30min and it wait at stand=30min.after this speed of return increases by 50%. so 50% of 18mph=9mphtotal speed of returning=18+9=27then in return it take 27/27=1hr.then total time in journey=1+1.30+0.30=3hrso it will come at 8+3hr=11am.so ans=11am
