The number of elements in the set S = {(x, y, z) : x, y, z in Z, x 2y 3z = 42, x, y, z ge 0} equals __________.

If x, y and z are three non-zero numbers such that x + y le z -x, y + z le x -y and z + x le y -z , the maximum value of x + y + z is __________.

Three positive distinct numbers x, y, z are three terms of geometric progression in an order and the numbers x + y, y + z, z + x are three terms of arithmetic progression in that order. Prove that x^x . y^y = x^y . Y^z . Z^x .

If x,y,z are three natural numbers in A.P. such that x+y+z=30 , then the possible number of ordered triplet (x, y, z) is :
