A printer begins printing forms at 9.33 AM,at the rate of 66 forms per minute ,another printer begins at 9.50 AM ,printing 77 forms per minute .
By the time , second printer starts, 1st printer has printed 66*17 forms.
second printer will be able to fill this gap @ 77-66=11 forms per minute.

so second printer will take 17*66/11 = 102 minutes = 1 hr 42 mins.

so two printers will have printed the same number of forms after 1 hr 42 mins from 9.50 AM i.e. at 11 :32 hrs

till 9.50 1st printer will print 17*66=1122 words
then x*77=x*66 +1122
11x=1122
x=102 min after 9.50
i.e. 11.32 AM
