A can copy 50 pages in 10hrs.
Therefore, In 1hr A can copy = 50/10 = 5pages
A and B can copy 70 pages in 10hrs.
i.e A + B =70
1hr A and B can type = 70/10 = 7pages
The given data's both A & A+B in 10 hrs only,
so, we can directly apply the A value in the A+B
A+B=7 (for 1hr)
5+B=7 => B=2 (B can type 2 pages in 1hr)
Therefore, for 1hr => 2 pages
Xhr => 26 pages
then Xhr = 13hr (by cross multiplication)
For B to type 26 pages in 13hrs.
