Find the value of $$\left(27 \times 3\right) \times \left\{(3 \div 3) \times \frac{(19 - 15)}{4} \right\}$$​​

Correct option is C

Given:
​$$\left(27 \times 3\right) \times \left\{(3 \div 3) \times \frac{(19 - 15)}{4} \right\}$$ 
Concept Used:

Solution: 
​$$\left(27 \times 3\right) \times \left\{(3 \div 3) \times \frac{(19 - 15)}{4} \right\} \\=\left(27 \times 3\right) \times \left\{1 \times \frac{4}{4} \right\}\\=\left(27 \times 3\right) \times \left\{1 \times 1 \right\}\\=81 \times 1\\=81$$​​
