Out of total number of 2807 women, who were interviewed for employment in a textile
factory, 912 were from textile areas and the rest from non-textile areas. Amongst the married
women, who belonged to textile areas, 347 were having some work experience and 173 did
not have work experience, while for non-textile areas the corresponding figures were 199
and 670 respectively. The total number of women having no experience was 1841 of whom
311 resided in textile areas. Of the total number of women, 1418 were unmarried and of
these the number of women having experience in the textile and non-textile areas was 254
and 166 respectively. Tabulate the above information. [CA. (Foundation), May 2000

The marginal cost of producing an additional shirt (that is, one more shirt than would maximize his profit) is , which is than the price Sam receives for each shirt he sells. Therefore, Sam's profit-maximizing quantity corresponds to the intersection of the curves. Because Sam is a price taker, this last condition can also be written as .arrow_forward
