since the distance travelled is same st=(s+0.5)(4/5)ton solvin u will get s=2there is one more equationst=(s-0.5)(t+5/2)substitute s=2 in the above eq and find 't' u will get s=2,t=7.5 therefore d=st=15kmans:15km

Time taken is same for both the ships & seaplanetime =distance/speed.....if speed of ship=s then seaplane speed=10slet distance of ship be x then seaplane distance =18+xtherefore (x / s = (18 + x ) / 10s)...then we get x = 2 therfore total distance = 18+2=20ans 20

A report consists of 20 sheets each of 55 lines and each such line consists of 65 characters. This report is retyped into sheets each of 65 lines such that each line consists of 70 characters. The % reduction in the number of sheets is closest to a) 20 b) 5 c) 30 d) 35

20 sheets 55 lines 65 characters?x?sheets?65 lines?70 characters=> x=(20*65*70)/65*55=25.45

20% is d ans20*55*65 = 71500 charsLet the number of sheets required be x here.Hence, x*65*70 = 71500 charsor x = 71500/65*70 = 15.71 = 16 sheets(approx)hence % reduction in sheets = 20%

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.

Program Memory Occupied
The size of a program is N. And the memory occupied 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?

NOW N=N+N/100=101N/100M=SR OF 100N=>SO SR OF 100*101/100ans is SR OF 101N

The memory size depends on the size of the program...If the program size is increased by 1%, then the memory size also changes according to size of the pgm...The new size of the program is n+n/100...and the size of memory is square root of 100(n+n/100)....

Points Collection
Given a collection of points P in the plane, a 1-set is a point in P that can be separated from the rest by a line, i.e the point lies on one side of the line while the others lie on the other side. The number of 1-sets of P is denoted by n1(P). The minimum value of n1(P) over all configurations P of 5 points in the plane in general position (.i.e no three points in P lie on a line) isa) 3 b)...
