An article is bought for Rs. 1,200 and Rs. 100 is spent on its transportation, etc. Find:
(i) the total C.P. of the article.
(ii) the selling price of it in order to gain 20% on the whole.

40 pens are bought at 4 for Rs. 50 and all of them are sold at 5 for Rs. 80 Find
(i) C.P. of one pen.
(ii) S/P. of one pen.
(iii) Profit made by selling one pen.
(iv) Profit percent made by selling one pen.
(v) C.P. of 40 pens
(vi) S.P. of 40 pens.
(vii) Profit made by selling 40 pens.
(viii) Profit percent made by selling 40 pens. Are the results of parts (iv) and (viii) same? What conclusion do you draw from the above result?

The C.P. of 5 identical articles is equal to S.P. of 4 articles. Calculate the profit percent or loss percent made if all the articles bought are sold.

The C.P. of 12 pens is same as S.P. of 15 pens. Calculate the profit or loss percent made, if all the pens bought are considered to be sold.
