What will come in place of question mark ‘?’ in the following question? (You do not have to calculate the exact value) 75.4 × 5.19 + 515.30 = 314.90 × ? – 54.73 Correct Answer 3
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,
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 the least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated.
Given Expression,
75.4 × 5.19 + 515.30 = 314.90 × ? – 54.73
We can also write values as:
75.4 ≈ 75, 5.19 ≈ 5, 515.30 ≈ 515, 314.90 ≈ 315, 54.73 ≈ 55
Given expression becomes,
⇒ 75 × 5 + 515 = 315 × ? – 55
⇒ 375 + 515 = 315 × ? - 55
⇒ 890 = 315 × ? - 55
⇒ 315 × ? = 945
⇒ ? ≈ 3
