​$$[\{(54.36 \times 0.4) + 0.256\} \div \sqrt{121}]$$​ equals:

Correct option is A

Given:

​$$[\{(54.36 \times 0.4) + 0.256\} \div \sqrt{121}]$$​​

Solution:

​$$[\{(54.36 \times 0.4) + 0.256\} \div \sqrt{121}]$$​​

= $$[\{(21.744) + 0.256\} \div 11]$$​​

= $$[\{22\} \div 11]$$​​

​$$= \frac{22}{11} =2$$​​
