if x = 1, 5, 7, 11, 13, 17, 19, 23 & y = 23, 19, 17, 13, 11, 7, 5, 1 respectively then (x*y + 1) & (x+y) will both be divisible by 24.
If x, y, z are 3 non zero positive integers such that x+y+z = 8 and xy+yz+zx = 20, then What would be minimum possible value of x*y^2*z^2
If x and y are the lengths of two sides of a triangle such that the product xy = 18, where x and y are integers, then how many such triangles are possible?
If x(x+y) = y(y+z) = z(z+x) and x,y,z are positive integers. Then is it definitely true that x=y=z
