Since there are only 3 colors the no of marbles needed to make any two same color is 4.Among the 4 marbles two of them will be the same color.

A train blows a siren one hour after starting from the station. After that it travels at 3/5th of its speed it reaches the next station 2 hours behind schedule. If it had a problem 50 miles farther from the previous case,it would have reached 40 minutes sooner. Find the distance between the two stations

Both the Guptas and Sinhas have two young sons, whose ages are under Eleven. The names of the boys, whose ages rounded off to the nearest year are all different, are Rajesh,Praveen, Lalith and Prathap. Taking the ages of the boys only to the nearest year, the following statements are true:-Rajesh is three years younger than his brother is.Praveen is the oldest.Prathap is 5 years older than the younger Sinha's boy.Lalith is half as old as one of the Guptha's boys.The total ages of the boys in each family differ by the same amount today as they did five years ago.

Prathap is 7 yrs old
Rajesh is 4 yrs old. Both of them are Guptas boys
Praveen is 8 yrs old. Lalith is 2 years old. both of them are sinhas boys.
The total age of each family now are

. two trains of length 1/6 miles are moving towardeach other with a speed of 60 miles per hour.aproaching toward each other In how much timethey will cover each other.ans.10 secPLEASE TELL THE APPROACH FOR TIS
atreya
- Aug 28th, 2012
Total dist travelled=(1/6+1/6)=1/3miles
relative speed=(60+60)=120miles per hour
therefore,
time=dist/speed
=(1/3)/120=(1/360)hours=10secs(1hr=3600secs).tmhasan7
- Sep 25th, 2006
1. Its obvious that since the trains travel towards each other the speed is 60+60 miles/hr2. The two trains will take 2/6 miles to cross themselves, since the length of the train is 1/6 miles.3. If it...

CORRECTION :There is a discrepancy of 5/11 mins in overlapping and it gains by this much time in 65 mins (Not 60 mins).................. Which means that :correct clock takes 65 & 5/11 ...

in a correct clock55 minutes are gained in 60 min60 min are gained in 60/55*60 min = 65 5/11 minbut now they got together in 65 minso gain in 65 min= (65 5/11 - 65) = 5/11 min

Finding Original Number Divided
Three friends divided some bullets equally. After all of them shot 4 bullets the total no.of remaining bullets is equal to that of one has after division. Find the original number divided?
Pradeep Narra
- Sep 3rd, 2010
Let x be the total number of bullets,x/3 will be each share...after each shooting 4 bullets..x/3 -4 will be there with each one..so suming them.....x-12 = x/3x = 18;

There is A one-way road one km long with two lanes, each lane five meters broad. Cars Cruise at 60 kmph on each lane. Distance between front bumpers of any two Successive cars is 10 meters which includes length of one car plus the clear Between the two cars. question (a): how many cars exit the road in one hour (your brilliant readers will find this childs play). then one morning mtnl digs a trench across one Lane at location half km of road length. The trench is 5m x 5m which makes a Single lane road for 10 meters (2.5 meters on either side of the trench for Maneuvering). As the driving discipline and etiquette of indian rivers is World famous they allow five cars from one lane and then five cars from The other lane to enter the single lane portion of the road.
