Just plug and chug. Since the question asks for percents, pick 100. (but any number will do.)

100/50 + 100/25= 2+4 =6

6 is 6% of 100.

a direct approach is also not bad

(3X/50)(100/X)=6

A lot of people jump to a smart number of 100. The confusing part can come when you are asking "what percent of x" (i.e "what percent of 100"). Therefore, you can avoid this by choosing a different smart number which is a multiple of 50 and 25 --> 50.


Therefore:
if X=50
\(\frac{50}{50}\) + \(\frac{50}{25}\) = 1 + 2 = 3

Because we need to figure out the percent of X, we must then take our new fraction \(\frac{3}{50}\) and multiply by 100 to form a percent. Cross multiplication will work fine. \(\frac{3}{50}\) = \(\frac{x}{100}\)

Notice that you can just multiple \(\frac{3}{50}\) * \(\frac{2}{2}\) because this is essentially multiplying by 1 and that will change the denominator to 100 leaving you with \(\frac{6}{100}\) or 6%

Written differently: notice that the denominator in \(\frac{3}{50}\) is 50. Thus, you can make the denominator 100 in order to get a percentage. To do so, you must multiply 50 * 2. Do not forget that if you multiply the denominator by 2, you must also multiply the numerator by 2.

Answer = A

Take x as 100.

x/50 + x/25 = 100/50 + 100/25 = 2 + 4 = 6

So 6%. Option A

A. 6%
B. 25%
C. 37 1/2%
D. 60%
E. 75%

\(\frac{x}{50} + \frac{x}{25} = \frac{3x}{50}\).

So, we need to find 3x/50 is what percent of x:

\(\frac{\frac{3x}{50}}{x}*100=6\%\).

Answer: A.
