Solve the following.
$$\left[\frac{(1+4-\frac{42}{14}+65)+\{\frac{(2+7×9)}{13}\}×[(65+7-19)]+(19-39×5)}{369}\right]$$​=?

Correct option is A

Solution:

​$$\left[\frac{(1+4-\frac{42}{14}+65)+\{\frac{(2+7×9)}{13}\}×[(65+7-19)]+(19-39×5)}{369}\right] \\ \ \\ = \left[\frac{(67)+\{5\}×[(53)]+(-176)}{369}\right]\\ \ \\ = \left[\frac{(67)+\{5\}×[(53)]+(-176)}{369}\right] \\ \ \\ = \frac{156}{369} \\ \ \\ = \frac{52}{123}$$​​
