Solution

## The correct option is B Rs 726The total cost to print 900 copies would be given by: Cost for setting up the type + cost of running the printing machine + cost of paper/ink etc 1000+120×9+900×0.6=1000+1080+540=2620 A 10% profit on this cost amounts to Rs 262. Hence, the total amount to be recovered is Rs 2882. Out of this, 784 copies are sold for Rs 2.75 each to recover Rs 2156. The remaining money has to be recovered through advertising. Hence, The money to be recovered through advertising = 2882 - 2156 = Rs 726. Option (c) is correct.
