Machine A and machine B are each used to manufacture 440 sprockets. It takes machine A 10 hours longer to produce 440 sprockets than machine B. Machine B produces 10% more sprockets per hour than machine A. How many sprockets per hour does machineAproduce?	Answers
A) 6	B) 6.6	C) 60	D) 4.4	E) 110
time taken by B = t   time taken by A = t+10   qty produced by A = q   qty produced by B = 1.1 q   for B: t(1.1q) =440   qt=400   for A: (t+10)(q) = 440   qt+10q=440   400+10q=440   q=4   so A can produce 4/hour.   then B can produce = 4(1.1)=4.4/hour.   4.4
