A) Machine M processes the product at a rate that is greater than 92 kilograms per hour
B) Machine M processes the product at a rate that is less than 95 kilograms per hour

Any ideas?
Thanks



This is how I tried.

We need to find the whether Machine A can process more than 25 grams per second.

From Stat 1 ) 92 * 1000 / 60 * 60 = 25.5 > 25 grams and if we consider some number greater than 92, for ex 93, 94,95 etc then the rate will be always greater 25.
From Stat 2 ) 95 * 1000 / 60 * 60 = 26.6 > 25. But we consider some number less 95, for ex 40,50 70 , 80 etc it will lesser than 25.

Option A is correct.

Will correct if the above method is incorrect.
