Ans: Since the computer can produce 1,76,400 lines in a day ie.in 24 hours. Then it can print 1,76,400 lines per 1440 minutes( 24 hours=1440 minutes).Then irrespective of the operational time it can print 122.5 lines in a minute.

Q.A computer printer produced 176,400 lines in a given day. If the printer was in operation for seven hours during the day, how many lines did it print per minute?
Ans. question says printer produces = 176,400 lines in a day
on the same day it worked = 7 hours
therefore,
printer producs 176,400 lines in 7 hours
=> 176,400 lines in ( 7*60 ) minutes
=> (176,400 / 420) lines per minute
=> 420 lines per minute
"420 lines/min."
