For B to operate the least amount of time A must operate for maximum time which is 8hrs. in 8hrs A will produce 9000* 8 = 72000 pencils and so B needs to produce the remaining pencils which is [100000 - 72000 = 28000].
Time required by B will be 28000/7000 = 4hrs

m/c A 9000 pencils per hr
m/c B 7000 pencils per hr

in certain period of time say x bth makes 100000
