What should come in place of question mark (?) in the following question?
1.05% of 110 + 1.05% of 130 = ?
Solution
Correct Answer: Option B
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.
Given expression,
1.05% of 110 + 1.05% of 130 = ?
\(\begin{array}{l} \Rightarrow ? = \frac{{1.05}}{{100}} \times 110 + \frac{{1.05}}{{100}} \times 130\;\\ \Rightarrow ? = \frac{{1.05}}{{100}} \times \left( {110 + 130} \right) \end{array}\)
⇒ ? = 2.52
