A bus started from bustand at 8.00a m and after 30 min staying at destination, it returned back to the bustand. the destination is 27 miles from the bustand. the speed of the bus 50 percent fast speed. at what time it returns to the bustand

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

U can writre the statement as1-(1/4)=3/41/4-(1/9)=5/361/9-(1/16)=7/144so continuing like that we get 1-(1/100)=.99

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.

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%

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 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,...

In a certain code, the symbol for 0 (zero) is. * and that for 1 is $. The numb.:rs greater than 1 are to be written only by using the two symbols given above. The value of the symbol for 1 doubles itself every time it shifts one place to the left.(For example, 4 is written as $**; and; 3 is written as $$)

First you have to find the binary value for that no. Then you can replace 1 by $ and 0 by *

Hello,Your Question is not properly questioned...But the logic behind is Its simple the BINARY CODING...With changed symbol....1=> $ and 0=> *simply in BINARY we can write 4 as '100' and 3 as '11'
