আমরা প্রদত্ত সমীকরণে বিকল্পগুলি প্রয়োগ করি এবং BODMAS নিয়ম ব্যবহার করে সমাধান করি:

প্রদত্ত সমীকরণ: 11 * 3 * 11 * 2 * 9 = 10

এখন, গাণিতিক অপারেটর দিয়ে * চিহ্নগুলি প্রতিস্থাপন করুন:

বিকল্প 1) x, ÷, −, +

11 x 3 ÷ 11 - 2 + 9 = 10

11 x 0.27 - 2 + 9 = 10

3 - 2 + 9 = 10

12 - 2 = 10

10 = 10

LHS = RHS.

বিকল্প 2) ÷, x, −, +

11 ÷ 3 x 11 - 2 + 9 = 10

3.6 x 11 - 2 + 9 = 10

40.3 - 2 + 9 = 10

49.3 - 2 = 10

47.310।

এলএইচএস ≠ আরএইচএস।

বিকল্প 3) ÷, +, −, x

11 ÷ 3 + 11 - 2 x 9 = 10

3.6 + 11 - 2 x 9 = 10

3.6 + 11 - 18 = 10

14.6 - 18 = 10

-3.410।

এলএইচএস ≠ আরএইচএস।

বিকল্প 4) x, ÷, +, −

11 x 3 ÷ 11 + 2 - 9 = 10

11 x 0.27 + 2 - 9 = 10

3 + 2 - 9 = 10

5 - 9 = 10

-410।

এলএইচএস ≠ আরএইচএস।

সুতরাং, সঠিক উত্তর হল "বিকল্প 1"।
