In 20 mins , A will print 60*20 = 1200 words.
The printer B can fill this gap @ 20 words per min.

Time taken by B to fill gap of 1200 words = 1200/20 = 60 mins.

so at 9.07 , printer B will catch printer A.

60*x=80*(x-20)
60X=80X-1600
20X=1600
x=80 mints
A s time is 7.47+80 mints=9.07

A prints 60 words/minute
B prints 80words/minute
it means b print 20 words more than A in per minute
therefore, if we calculate for 20 minute then A prints 1200 words
then,
1200 words prints by B in 20 minute is 1200/20 = 60 minute
therefore B vil catch A at 9:07

The gap between time A and time B is 20 minutes therefore
In 20 mins , A will print 60*20 = 1200 words.
The printer B can fill this gap @ 20 words per min.

Time is taken by B to fill a gap of 1200 words = 1200/20 = 60 mins.

so at 9.07 , printer B will catch printer A.
