G(6)=g(5)+g(4)g(5)=g(4)+g(3)g(4)=g(3)+g(2)g(3)=g(2)+g(1)g(2)=g(1)+g(0)=1+1=2S0, g(3)=2+1=3g(4)=3+2=5g(5)=5+3=8g(6)=8+5=13

G(6)= g(5)+g(4)g(4)= g(3)+g(2)g(2)= g(1)+g(0)= 2 (Given in ques g(0)=g(1)=1)So, g(3)= g(2)+g(1)= 2+1= 3Also, g(4)= g(3)+g(2)= 3+2= 5Similarly, g(5)= g(4)+g(3)= 5+3=8And hence, g(6)= g(5)+g(4)= 8+5= 13 -ANS

4.In two dimensional array X(7,9) each element occupies 2 bytes of memory.If the address of first element X(1,1)is 1258 then what will be the address of the element X(5,8) ? whats the ans
bangalo

The answer is1) If it is a row based then 1258+2(9(5-1)+(8-1))=1258+2(36+7)=1258+86=13442)
If it is column based then1258+2((7(8-1)+(5-1))=1258+2(49+4)=1258+106=1364. -
What is the difference between "overloading" and "overridding"?
nebudotcom
- Aug 5th, 2010
Overloading:Using more than one function with the same name but with different signatures Overriding:* Two functions having same name located in two different classes* When an object is created for subclass, it will override the baseclass ie the subclass function will get evoked.

Overloading, an assignment operator is overloaded in a base class, it cannot be inherited in a derived class. And overriding is to create a new class using derived class.

If log(3.14) and log(3.16) are given, What is the value of log(3.15)?
gkrishna990
- Jul 4th, 2010
Log(3.14)=log(3.15-.01)=log(3.15)/log(.01)Having known the values of log(3.14) and log(.01) on cross multiplying we get log(3.15)
decentshabbir
- Oct 8th, 2008
Log(3.15) = log(3.14 + 0.01) log(3.15) = log(3.16 - 0.01) log(3.15)* log(3.15)= log(3.14) * log(0.01) * log (3.16) / log(0.01) log(3.15)* log(3.15)= log(3.14) * log (3.16) 2 * log(3.15)= (log(3.14) * log (3.16) ) log(3.15)= (log(3.14) * log (3.16) )/2

Alpine tunnels are closed tunnels. In the past 30 yrs not even a single accident has been recorded for there is one accident in the railroad system. Even in case of a fire accident it is possible to shift the passengers into adjacent wagons and even the living fire can be detected and extinguished with in the duration of 30 min.
no accident can occur in the closed tunnels (True/False/Can't Say)fire is allowed to live for 30 min.(True/False/Can't Say)All the care that travel in the tunnels will be carried by rail shutters.(True/False/Can't Say)

1. False.2. Cannot say because the maximum limit for fire prevailing is 30mins, it may well be put off earlier than that.3. Cannot say - nothing is mentioned on that.

1) Can't say (bz it is said that no accident has been recoreded bt it does not mean that noaccident can occur. It can occur, there is a possibility of it.)2) True (bz it is said that fire can be extinguished in 30 minutes.) 3) Can't say (bz nothins is said about rail shutters)

electronics technology is coming to the rescue of helicopters which can be grounded or crash in icy conditions the machines are especially vulnerable to the build up of ice on both their rotors and engine air intake when operating in cold damp conditions. the problem is 2 fold ice increases the weight and the build up makes the aerofoils less efficient .now at last a detector has been devised which the company hopes will means after flights and less frequent grounding. unlike most devices in use at present it can detect the liquid water content of cloud above freezing level. so the warning is given before the potential hazard is encountered.
an electronic device has been invented which will prevent he build up of ice on helicopter rotors (True/False/Can't say)helicopters are sometimes grounded because in cold damp weather their engine air intakes and rotors malfunction owing to the formation of ice.

File Transfer
A file is transferred from one location to another in 'buckets'. The size of the bucket is 10 kilobytes. The bucket gets filled at the rate of 0.0001 kilobytes per millisecond. The transmission time from sender to receiver is 10 milliseconds per bucket. After the receipt of the bucket the receiver sends an acknowledgement that reaches sender in 100 milliseconds. Assuming no error during transmission,...

balls
A sporting goods store ordered an equal number of white and yellow balls.The tennis ball company delivered 45 extra white balls,making the ratio of white balls to yellow balls 1/5 :1/6how many white balls did the store originally order for?a)450 b)270 c)225 d)none of these
anilkumar_cse
- Apr 1st, 2010
Given ratio is of white and yellow balls and it is 1/5:1/6.=> 6:5=> Therefore the total balls are in 11 parts.=> so the total balls delivered must be divided by 11.=> From the answers 450 + 45 is divided by 11, so the answer is a=>450

ans is 16 percentlet T eqals = -t^2/6+4*t+12 ( where t is elapsed time)rate of change in temp. eqals dT/dtdat is -4t^2-36t/(18+4*T)^2here time elapsed is 3putting the value t eqal 3we get 144/900so percentade change(144/900)*100ans 16 percent

Power cable question
A power cable is to be run from a power plant on the bank of a river 900 meters wide to a factory that is located 3000 meters downstream on the opposite bank. If the cost of laying cable under water is Rs. 5 per meter and that of laying overhead on land is Rs. 4 per meter, find the point downstream where the cable is to cut across the river.

I do not think it is complex. They give cost to plant the cable in ground and water both also
Let assume the length across the river is x;By given cost 5x=4*3000+5*900so x=3300 3300/2=1650so the point is 1650m from x axis, and 450m(half of distance bet banks) from y axis(450,1650)
