Follow BODMAS rule to solve this question, as per the order given below,

Step-1-Parts of an equation enclosed in 'Brackets' must be solved first,

Step-2-Any mathematical 'Of' or 'Exponent' must be solved next,

Step-3-Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated,

Step-4-Last but not least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated.

Now, the given expression,

$(\begin{array}{l} {11^2} - {6^2} \div 6 \times \frac{5}{2} - 2\;of\;5 = ?\\ \Rightarrow \;?\; = 121 - \frac{{36}}{6} \times \frac{5}{2} - 10 \end{array})$

⇒ ? = 121 – 15 – 10

⇒ ? = 96
