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, the BODMAS rule must be followed,

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.

4015 × 73 - 21817 = ? × 112 + 126

⇒ 293095 - 21817 = ? × 112 + 126

⇒ 271278 = ? × 112 + 126

⇒ ? × 112 = 271278 - 126

⇒ ? = 271152/112
