Follow these BODMAS rules to solve the question
Step -1: The part of the equation containing '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 solved
Step -4: At last, the parts of the equation that contain 'Addition' and 'Subtraction' should be solved.
⇒ [(130)2 ÷ 25 × 75] ÷ 30 = ? + 1500
⇒ [(130 × 130 × 75) /25] ÷ 30= ? + 1500
⇒ (130 × 130 × 3) ÷ 30 = ? + 1500
⇒ 1690 – 1500 = ?
∴ ? = 190
