A. 40%
B. 50%
C. 60%
D. 70%
E. 80%



Let y = 20.........(2y)/20 + (3y)/10 = (2 *20)/20 + (3 * 20)/10 = 8

The 8/20 = 2/5 =0.4 = 40%

\(\frac{2y}{20} + \frac{3y}{10}\)

\(\frac{8y}{20}\)

\(\frac{2y}{5}* 100\)

\(40%\)

(A)

Solution:



Approach and Working

To find, \(\frac{(2y)}{20} + \frac{(3y)}{10}\) is what percent of y, we first have to calculate the value of \(\frac{(2y)}{20} + \frac{(3y)}{10}\).
    • \(\frac{(2y)}{20} + \frac{(3y)}{10}\) = \(\frac{(2y+ 3y*2)}{20}\)
    • \(\frac{8y}{20}\)= \(\frac{2y}{5}\)

Now, we can easily find \(\frac{2y}{5}\) is what percentage of y.

• \(\frac{2y}{5} /y\) *100= 40%

Hence, the correct answer is option A.

Answer: A
