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: Finally, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated. ⇒ 12 × 117 ÷ 9 + 206 = 20 + ? × 4 ⇒ 12 × 13 + 206 = 20 + ? × 4 ⇒ 156 + 206 = 20 + ? × 4 ⇒ 362 = 20 + ? × 4 ⇒ 362 – 20 = ? × 4 ⇒ 342 ÷ 4= ? ∴ ? = 85.5

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: Finally, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated.

⇒ 12 × 117 ÷ 9 + 206 = 20 + ? × 4

⇒ 12 × 13 + 206 = 20 + ? × 4

⇒ 156 + 206 = 20 + ? × 4

⇒ 362 = 20 + ? × 4

⇒ 362 – 20 = ? × 4

⇒ 342 ÷ 4= ?

∴ ? = 85.5
