Correct option is A

Given: ​

​$$\left( 90\div 5 \right) \times \left\{ \frac{78}{6} + \frac{12}{1} \times (8 - 7) \right\}$$ 

Concept Used: ​

Solution: ​

​$$\left( 90\div 5 \right) \times \left\{ \frac{78}{6} + \frac{12}{1} \times (8 - 7) \right\} \\ \ \\ =\left( 18 \right) \times \left\{ \frac{78}{6} + \frac{12}{1} \times (1) \right\} \\ \ \\ =\left( 18 \right) \times \left\{ 13 + 12 \right\} \\ \ \\ =\left( 18 \right) \times \left\{ 25 \right\} \\ \ \\ =\left( 18 \right) \times \left\{ 25 \right\}\\ \ \\ = 450$$​​
