What approximate value should come in place of question mark (?) in the following question? 4.897 × 4.010 + 6.021 ÷ 1.899 – 2.967 × 3.033 = ?
What approximate value should come in place of question mark (?) in the following question? 4.897 × 4.010 + 6.021 ÷ 1.899 – 2.967 × 3.033 = ? Correct Answer 14
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 least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated.
Given expression is,
4.897 × 4.010 + 6.021 ÷ 1.899 – 2.967 × 3.033 = ?
Taking their approx. values
⇒ 5 × 4 + 6 ÷ 2 – 3 × 3 = ?
⇒ ? = 20 + 3 – 9
⇒ ? = 14
∴ ? = 14
