Answer» 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, [(6878 + 1333 - 8031) - (12.02 × 1.99 × 7.09)] × 2.532 = ? Taking approximate values as, 12.02 ≈ 12, 1.99 ≈ 2, 7.09 ≈ 7, 2.532 ≈ 2.5 ⇒ [180 - (12 × 2 × 7)] × 2.5 = ? ⇒ [180 - 168] × 2.5 = ? ⇒ 12 × 2.5 = ? ∴ ? = 30

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,

[(6878 + 1333 - 8031) - (12.02 × 1.99 × 7.09)] × 2.532 = ?

Taking approximate values as,

12.02 ≈ 12, 1.99 ≈ 2, 7.09 ≈ 7, 2.532 ≈ 2.5

⇒ [180 - (12 × 2 × 7)] × 2.5 = ?

⇒ [180 - 168] × 2.5 = ?

⇒ 12 × 2.5 = ?

∴ ? = 30
