The way to solve this is to know how to change from from fractions to percentage. if A [%] = A/100 so B = 100B [%]. Lets apply this idea to the question: Y = X*m[%] = X*m/100 Therefore, X=Y*100/m. The answer needs to be in percentage, so we need to change again. if B = 100/m so B[%] = 100*100/m = 10...

So the price intended by the seller in order to gain 20 percent was 1.2$ for every lb. So the total should be 900*1.2 = 1080$. When checking for the gain we see that he actually rece...

In order to find the value of the sum of series we can use this equation: (Series' average)*(number of elements) = Sum In this case we can look at the question as a series of the multiplies of 7 from 105 to 196. Thus, average = (105 + 196)/2 = 150.5 number of elements = (196 - 105)/7 + 1 = 14 Theref...

Lets look at each statement separately. (1) x = 0.5 + y This does not tell us anything about the values of x and y. Only the relation between them. Therefore, insufficient. (2) x/y > 1 lets use some numbers x=2, y=0.5 x/y=4>2 x=-2, y=-0.5 x/y=4>2. Therefore, insufficient. (1)+(2) lets place the firs...
