Simplify the following.

​$$\frac{\frac{6}{7} + \frac{2}{3}}{\frac{1}{6} -\frac{3}{20}}$$​​

Correct option is A

Given:

​$$\frac{\frac{6}{7} + \frac{2}{3}}{\frac{1}{6} -\frac{3}{20}}$$​​

Solution:

​$$\frac{\frac{6}{7} + \frac{2}{3}}{\frac{1}{6} -\frac{3}{20}}$$​ 

= $$\frac{\frac{18+14}{21}}{\frac{10-9}{60} }$$​​

= $$\frac{\frac{32}{7}}{\frac{1}{20} }$$​​

= $$\frac{640}{7}$$​​
