A traveler walks a certain distance. Had he gone half a kilometer an hour faster , he would have walked it in 4/5 of the time, and had he gone half a Kilometer an hour slower, he would have walked 2 ½ hr longer. What is the distance?

There'll be 3 eq...t - timed - distances - speedd/t=s d/(4/5)t=s+1/2d/(t+(5/2))=s-(1/2)solve it....u'll getd=15...hope im correct

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. (a) 450 (b) 3900 (c) 1800 (d) 2100 (e) 2700

The cost calculation what i said previously was wrong.its 3000*4 + 2100*4=20400.

Which of the following is not an infinite loop?A. while(1){ ....}B. for(;;){...}C. x=0; do{ /*x unaltered within the loop*/ .....}while(x = = 0);D. # define TRUE 0 ... while(TRUE){ ....}

It is not c) becoz in while loop comparision takes place that is 0==0(which is true and returns the value 1) so while loop executes and it goes in infinite loop. The correct answer is (D) becoz in while loop condition becomes false with zero(0) and never enters into the loop.

20 sheets,55 lines and 65 characters implies 20*55*65=71500.x sheets,65 lines and 70 characters implies x*65*70=71500.therefore x=16.so 16 sheets.reduction: ((20-16)/20) *100 =20%ans: 20%

What is the highest prime number that can be storedin a 8-bit microprocessor?
whats the method to find the answer...... plz any one tel me
chandradeepika
- May 28th, 2008
8-bit===>2^8=256.so the number must be below 256. so the answer is 251.

Guys the formula is (2^n)-1 n==>2,4,8,16, bit memory. this gives the max no and by reducing the max no we get largest prime no.

The size of a program is N. And the memoryoccupied by the program is given by M = square root of 100N. If the size of the program is increased by 1%then how much memory now occupied ?
plz any one tell me,how to answer this....

M1=sqrt(S1)=sqrt(100N)S2=101%S1=1.01NM2=sqrt(S2)=sqrt(100*(1.01N))=sqrt(101N)% increase is := (((sqrt(101N)-sqrt(100N))/sqrt(100N))*100)=(((sqrt(101)-10)/10)*100)%=((10*sqrt(101))-100)%=((10*10.05)-100)%=(100.5-100)%=0.5%

An aircraft takes off from A (72° N Lat, 40° E Long) at 2.00 Am local time to B (32° N Lat, 50° W Long). If the flying time is 10 hours what is the local time of landing at B?

40+50 =90. for 1 deg 4 minutes, so for 90 (90*4)=360minutes =6hours 2am+10hours journey-6hours=6hours.so the answer is 6am.

A file is transferred from one location to
A file is transferred from one location to another in 'buckets'. The size of the bucket is 10 kilobytes. Each 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,...
