Find the value of $$\quad \left[\left(\frac{63}{9}\right) \times \left\{\left(\frac{14}{7}\right) + \left(\frac{19}{1}\right) \times (7 - 6)\right\}\right] \\$$​

Correct option is D

Given:

$$\quad \left[\left(\frac{63}{9}\right) \times \left\{\left(\frac{14}{7}\right) + \left(\frac{19}{1}\right) \times (7 - 6)\right\}\right] \\$$

Solution:

​$$\quad \left[\left(\frac{63}{9}\right) \times \left\{\left(\frac{14}{7}\right) + \left(\frac{19}{1}\right) \times (7 - 6)\right\}\right] \\\ \\= \left[7 \times \left\{2 + 19 \times 1\right\}\right] \\\ \\= \left[7 \times \left(2 + 19\right)\right] \\\ \\= \left[7 \times 21\right] \\\ \\= 147$$​​
