A factory recycles paper for its own use.

Eight sheets of paper are required to make each new sheet.

From 981 sheets of paper to be recycled, how many sheets can possibly be made in total?

Answer is 140.

981/8=122(new) + 5(old)

122/8=15(new)+ 5(old)

15/8=1(new)+ 7(old)

5+5+7=17(old)

17/8=2(new)+ 1(old)

Total new sheets recycled are 122+15+1+2 =140
