What should come in place of the question mark (?) in the following question?
?% of 280 + 18% of (2200 ÷ 4) = 143.8
Correct Answer: Option D
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, and in the bracket, the BODMAS rule must be followed,
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 is,
⇒ ?% of 280 + 18% of (2200 ÷ 4) = 143.8
⇒ ?% of 280 + 18% of 550 = 143.8
⇒ ?% of 280 + 99 = 143.8
⇒ ?% of 280 = 44.8
⇒ (?/100) × 280 = 44.8
⇒ (?/100) = 44.8/280
⇒ (?/100) = 0.16
⇒ ? = 16
Hence required answer is 16.
