Simplify: $$\frac{6}{10} - \left( 0.6 \div \frac{10}{3} \text{ of } 0.6 + 7 - 10 \div 5 \right) - 0.3$$​​

Correct option is A

Given:

​$$\frac{6}{10} - \left( 0.6 \div \frac{10}{3} \text{ of } 0.6 + 7 - 10 \div 5 \right) - 0.3$$ 

Concept Used: ​

Solution: ​

​$$\frac{6}{10} - \left( 0.6 \div \frac{10}{3} \text{ of } 0.6 + 7 - 10 \div 5 \right) - 0.3 \\ \ \\ = \frac{6}{10} - \left( 0.6 \div 0.2 + 7 - 10 \div 5 \right) - 0.3 \\ \ \\ = \frac{6}{10} - \left( 0.3 + 7 - 10 \div 5 \right) - 0.3 \\ \ \\\\ \ \\ = \frac{6}{10} - \left( 0.3 + 7 - 2 \right) - 0.3 \\ \ \\ = \frac{6}{10} - \left( 5.3 \right) - 0.3 \\ \ \\ = 0.6-5.6 \\ \ \\ = -5$$​​
