In how many ways can four friends, Bheem, Chutki, Raju and Jaggu, share 50 laddoos among themselves, such that each of them gets an odd number of laddoos? How i approached this question is: B+C+R+J=50; Since each one of them can only have odd number of laddoos so each has number of laddoos of the form (2K+1). Hence, (2B+1)+(2C+1)+(2R+1)+(2J+1)=50>> B+C+R+J=23; Therefore, 23+4-1C4-1= 26C3=2600. Now, in the explanation for this question, the equation formed is different. Is what i'm doing wrong? @summi_arora
There are 13 equidistant bus stops on a straight road. A bus running at 60 km/hr is some distance away from the 1st stop from where it will move towards the 13th stop. Two cars start running from the 6th stop in opposite directions with the same speed. If the bus meets one of the cars at the 1st stop and the other at the 13th stop, then find the speed of the cars.
