Answer / apoorva
A can copy 50pages in 10hrs;
B can copy 70 pages in 10hrs;
Both A And B togethr ie (A+B) can copy 70 pgs in 10hrs;
which means B alone can copy 20 pages in 10 hrs (since A can copy 50pages in 10hrs;) ie (B-A)
hence if B can copy 20 pages in 10 hrs then in 24 hrs he can copy ((26*10)/20) = 13 hrs

A can copy 50 papers in 10 Hrs
A+B can copy 70 papers in 10Hrs
B can copy 26 papers in xHrs
i.e A+B-A=70-50=20papers in 10Hrs
Then 26 papers in xHrs
20papers in 10Hrs
x=260/20=13Hrs
So,B can copy 26 papers in 13Hrs.

Answer / dinesh kumar
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.

Answer / pankaj
A can copy 50 pages in 10 hrs.
A can copy 5 pages in 1hr.(50/10)
now A & B can copy 70 pages in 10hrs.
thus, B can copy 90 pages in 10 hrs.[eqn. is (50+x)/2=70, where x–> no. of pages B can copy in 10 hrs.]
so, B can copy 9 pages in 1hr.
therefore, to copy 26 pages B will need almost 3hrs.
since in 3hrs B can copy 27 pages.
