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.

1124 + [24 + {23 – (27 + 6 × 9) + 91} + 66.67% of 75] = ?2 + 270

⇒ 1124 + [24 + {23 – (27 + 54) + 91} + 2/3 × 75] = ?2 + 270

⇒ 1124 + [24 + {23 – 81 + 91} + 2 × 25] = ?2 + 270

⇒ 1124 + [24 + 33 + 50] = ?2 + 270

⇒ 1124 + 107 = ?2 + 270

⇒ ?2 = 1231 – 270 = 961

∴ ? = 31
