1. If x exceeds y by 2/3, y is what fraction of x?
2. A gain of 25% on the Cost of an article is equivalent to a gain of r% on the selling price of the article. What is value of r? Any help would be greatly appreciated. Thanks. Fuzz |

Answer to Q 2 :
Assume that the cost of an article is 100. Hence, gain on the cost = 100 * 25% = 25. Therefore, Selling price of an article is 100+25= 125. Now, 125 * r% = 25 Therefore, r = ( 25 * 100 )/125 = 20% Alternatively, 25% = 1/4 If cost of an article is x, then the gain is x/4 and the selling price will be x+ x/4 = 5x/4. gain = x/4 which is 1/5 * 5x /4 1/5 = 20 % hence r = 20% Hope this helps 1. I am not sure of this one but here is a possible solution: x= y+2/3 therefore y/x = y/ (y+2/3) that is = y/ ((3y+2)/3) That is 3y/3y+2 If a value is expected here, then something is missing from the stem. |
