Robots X,Y, Z each assemble components at their respective constant rates. If rx is the ratio of robot X's constant rate to robot Z's constant rate and ry is the ratio of robot Y's constatnt rate to robot Z's constant rate, is robot Z's constant rate the greatest of the three?

(1) rx < ry
(2) ry<1

Let rates be X, Y, Z

(1) rx < ry

X/Z <Y> X we cannot say anyting abt Z i.e it can be less than Y, greater than Y (greatest) .....

(2) ry<1

i.e Y/Z < 1 i.e Y <Z> X & Y < Z

Z is greatest SUFF
