Read Solution (Total 1)

A can copy 70 papers in 14 hours while both A & B can copy 110 papers in 19 hours.

A can copy 5 papers in 1 hr.
A can copy 95 papers in 19 hrs.
B can copy 15 papers in 19 hrs or 15/19 paper in 1 hr
So B needs 19/15 hrs for 1 paper

so B will take (44*19/15) hrs to copy 44 papers.
