9. A certain business printer can print 40 characters per second, which is 4 times as fast as an average printer. If an average printer can print 5 times as fast as an electric typewriter, how many characters per minute can an electric typewriter print?
(A) 2
(B) 32
(C) 50
(D) 120
(E) 600

Could anyone point out the right answer for me?

thanks

I figured out guys...it's a bit tricky. The answer is actually 2 Characters/Sec which is equivalent to 120 characters/minute.

I marked A initially but then i re read the question it just clicked chars/min hence IMO D

God save us from tricky wording !!
I think quant questions need to be re read several times if one finds them a bit easy !!
