What approximate value should come in place of the question mark (?) in the following question? (90.1 + 181.89) ÷ 4.10 + 262.30 = ? % of 8250.054

What approximate value should come in place of the question mark (?) in the following question? (90.1 + 181.89) ÷ 4.10 + 262.30 = ? % of 8250.054 Correct Answer 4

Rules of Approximation:

1. If a number has digits to the right of the decimal less than 5, then just drop the digits to the right of the decimal. The number so obtained will be the approximated value.

2. If a number has digits to the right of the decimal more than 5, then just drop the digits to the right of the decimal and raise the remaining number by '1'.The number so obtained will be the approximated value.

Concept:

Follow BODMAS rule to solve this question, as per the order is 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

(90.1 + 181.189) ÷ 4.10 + 262.30 = ? % of 8250.054

We can also write values as:

90.1 ≈ 90, 181.89 ≈ 182, 4.10 ≈ 4, 262.30 ≈ 262, 8250.054 ≈ 8250

Calculation:

Given expression becomes,

⇒ (90 + 182) ÷ 4 + 262 = ? % of 8250

⇒ 272 ÷ 4 + 262 = ?% of 8250

⇒ 68 + 262 = ?% of 8250

⇒ 330 = ?% of 8250

⇒ 330/8250 = ?/100

⇒ 33/825 = ?/100

⇒ 3/75 = ?/100

⇒ 1/25 = ?/100

⇒ 100/25 = ?

⇒ ? ≈ 4
