If pencils are bought at 70 cents per dozen and sold at 3 for 20 cents the total profit on 6 dozen is?

First, we need to restate the problem as thus: For every 70 cents, one can buy 72 pencils (equal to 6 dozen pencils). Thus, for every x cents, one can buy 3 pencils. In numerical form, this equation turns into $0.70/72 pencils = $x/3 pencils, or 0.70/72 = x/3. Simplified, one gets (3)(0.70) = 72x, or 2.1 = 72x. Hence, x=2.1/72=0.029, or $0.03, or 3 cents. So 3 pencils actually cost 3 cents. If one were to sell 3 pencils for 20 cents, one would have a profit of 17 cents for 3 pencils.

How much do 20 pencil cost if 4 pencils cost rupees three?

To help you understand this question, we will create a new temporary word. We will call every 4 pencils a "pencilor". So a "pencilor" cost 3 rupees. How many "pencilor" is there in 20 pencils? Well, 20 = 4 x 5, meaning there are 5 groups of 4 => there are 5 "pencilors". If each "pencilor" cost 3 rupees, how much does 5 cost? 3 x 5 = 15 rupees. And you are done.
