What approximate will come in the place of the question mark ‘?’ in the following question? ? = (2.402)2 – (0.488)1/2 + 1.06 of (72.798 ÷ 582.42)
What approximate will come in the place of the question mark ‘?’ in the following question? ? = (2.402)2 – (0.488)1/2 + 1.06 of (72.798 ÷ 582.42) Correct Answer <span style="font-family:calibri,sans-serif">5.2</span>
Concept:
Rules of Approximation:
1. If a number have digits to the right of the decimal less than 5. Then just drop the digits to the right of the decimals. The number so obtained will be the approximated value.
2. If a number have digits to the right of the decimal more than 5. Then just drop the digits to the right of the decimals and raise the remaining number by '1'.The number so obtained will be the approximated value.
Calculation:
Follow BODMAS rule to solve this question, as per the order given below,
⇒ ? = (2.402)2 – (0.488)1/2 + 1.06 of (72.798 ÷ 582.42)
⇒ ? = (2.4)2 – (0.49)1/2 + 1.06 of (72.8 ÷ 582.4)
⇒ ? = 5.76 – 0.7 + 1.06 of 1/8
⇒ ? = 5.76 – 0.7 + 0.13
⇒ ? = 5.19
⇒ ? ≈ 5.2
∴ The value of ? is 5.2
