x=k/(y*y). From given data 4=k/(3*3) gives k=36 Thus x=36/(y*y) When y=6, x=36/(6*6) means x=1 answer
S varies directly as R varies and T varies inversely as R varies. At a time R = 20, S = 40 and T = 10. If R is changed to 10, then what will be the value of T ?
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
