Find the value of $$\left( 17 \times 10 \right) \times \left\{ {8}\div{8} \times \left( \frac{19 - 12}{7} \right) \right\}$$​​

Correct option is D

Given: ​

​$$\left( 17 \times 10 \right) \times \left\{ {8}\div{8} \times \left( \frac{19 - 12}{7} \right) \right\}$$ 

Concept Used: ​

 Solution: ​

​$$\left( 17 \times 10 \right) \times \left\{ {8}\div{8} \times \left( \frac{19 - 12}{7} \right) \right\} \\ \ \\ =\left( 170 \right) \times \left\{ {8}\div{8} \times \left( \frac{7}{7} \right) \right\} \\ \ \\ =\left( 170 \right) \times \left\{ 1 \times 1 \right\}\\ \ \\ =\left( 170 \right) \times \left\{ 1 \right\} \\ \ \\ = 170$$​​
