The value of 

​$$\frac{2}{8} + \frac{3}{8} + \frac{3}{16} + \frac{4}{8} - 4 =$$​​

Correct option is C

Given:

$$\frac{2}{8} + \frac{3}{8} + \frac{3}{16} + \frac{4}{8} - 4$$

Solution:

$$\frac{2}{8} + \frac{3}{8} + \frac{3}{16} + \frac{4}{8} - 4$$

=$$\frac{4+6+3+8 -64}{16}$$

= $$- \frac{43}{16}$$

Option (C) is right.
