A traveler walks a certain distance
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 � hr longer. What is the distance?
RAJUTHAI
- Mar 8th, 2012
Ans:15km
solution:
speed(s)*time(t)=distance(d)
walked 1/2km with time 4/5
(s+0.5)((4/5)t)=d --->(1)
1/2km an hour slow, walked 2and half hr long
(s-0.5)(t+2.5)=d ----->(2)
solving (1) & (2)
we get s=2
t=7.5
d=2*7.5=15kmAkshujain

D = 15 kmsx = speed in km/hry = time takend / x = y - eq1d / x + .5 = (4/5)*y - eq 2d / x - .5 = 2.5 + y - eq 3 solving these three equation we get d = 15 x = 2 y = 7.5

bus
A non stop bus to Amritsar overtakes an auto also moving towards Amritsar at 10 am. The bus reaches Amritsar at 12.30 pm and starts on the return journey after 1 hr. On the way back it meets the auto at 2 pm. At what time the auto will reach Amritsar?
santhakumar.mit
- Aug 28th, 2010
Totally bus takes 2.30hrs to reach the Amristar.
So 1/5 of i.e 30 mins reach the one place where it met auto.
That means 4/5 of this travel by bus is 2hrs and auto is 4hrs
so2:4::1/2:x
2/4=1/2x
4x=4
x=1
so auto will reach Amirstar at 1hr.

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.

u have to pull 3 socks so that u get 1 correct pair...... first attempt - 1(black or white) 2nd-1(black or white)3rd -pair (u get any pair)

Circular Track
In a circular race track of length 100 m, three persons A, B and C start together. A and B start in the same direction at speeds of 10 m/s and 8 m/s respectively. While C runs in the opposite at 15 m/s. When will all the three meet for the first time on the after the start? with steps
pramoth
- Dec 25th, 2011
The three will never meet at the same place after they start because two people are running in the same direction with different speeds. so C will meet either A or B. but not both.

A sum of money is divided among A, B and C such that for each rupee A gets, B gets 65paise and C gets 35paise. If C's share is Rs.560, the sum is � ?
Akshujain
- Oct 26th, 2009
Let x = rupees divided among b and cGiven x * 35/100=560x*65/100=560*65/35=> x = 10401040+ 560 = 1600and from the question we can say that a gets double of share which b and c together gets=> a's share is 3200
pawansharma1987

C's share = 560 which is 35/200 of total sum.Total sum be x (35/200) * x =560x=3200 Rs.

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%

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,...

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

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
SpandanaMohan
- May 21st, 2008
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)....
