plz solve this questn and explain it.. i am facing problm in this..a function f(z1,z2,z3........,zn)= f(z1,zn)+ f(z2,z3,z4....., z(n-1))+ (z1+z2+z3.....+zn); for n>0 f(y,z)=f(z,0)+ f(0,y)f(y,0)= y+ f(y-1,0)f(0,y)= y- f(0,y-1)f(0,0)=1find the value of f(1,2,3,4,...........,n), where n is a perfect cube less than 50 and n is greater than 25 1) 1665 2) 1089 3) 729 4) not defined
Appu and Gappu both start running around a circular racetrack in the same direction, each of them going at a constant speed. Appu is on bicycle and Gappu is on foot. Appu goes all the way around the track and catches up with Gappu. The moment he meets Gappu, he turns around and heads back towards the starting point while Gappu keeps going on his path.
When Appu reaches the starting point he again meets Gappu who is just finishing his first round.
The ratio of the speeds of appu and gappu?pls post the aaproach 1) 1+root(2) : 1 2) 2:1 3) 3:1 4) 4:1 5) NOT
