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
a
d
let, b=business printer
a= avg. printer
e= elec. printer
b=4a
a=5e
but,b=40 char/sec
40=4a
a=10
now, 10=5e
thus, e=2 char/sec(A)
it is A
to all..
2 char/Sec is correct..but acc to question..wht is the no of charcters per minute
it is 2×60 = 120…
so ans is D
its 120
its 120 becz its char/min…
A
oopss 2*60=120 char/min answer D
d

u probably dont get ques easier than this one…..the correct ans for sure is a i.e 2 characters per second….
yes ans is D.. it can be easily mistaken if you dont read the question carefully..
i think the answer is d
answer is [d]
d. but its tricky cos it can be easily missed if not read closely.
no doubt is D
ofcourse the ans is D,
y is it confusing, tht so clearly given (per minute)……
2*60*60/60=120
hey Take GRE team or anyone else: please tell me where i can get Big Book. am really looking for it.
the ans is D.
D
average printer speed = 10 c/sec.
therefore electric one has speed = 10/5 = 2c/sec
therefore 2 * 60 = 120 c in 1 minute
ans is D
d..for sure..
the ans is [D]as the no of char that a typewriter can print per 1sec is 2…hence the no of characters that it can print in 1min is 2.60=120 char/min
ans is 120
yeah ans is d
let, b=business printer
a= avg. printer
e= elec. printer
b=4a
a=5e
but,b=40 char/sec
40=4a
a=10
now, 10=5e
thus, e=2 char/sec
but he e for min
e=2*60=120
ans:(d)120
