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,

17.94% of 250 + √2810 - 23.87% of 350 = ?

Taking the approximate values as,

17.94 ≈ 18, √2810 ≈ √2809, 23.87 ≈ 24

⇒ 18% of 250 + √2809 - 24% of 350 = ?

⇒ 0.18 × 250 + 53 - 0.24 × 350 = ?

45 + 53 - 84 = ?

∴ ? = 14
