Detailed Solution
Download Solution PDFপ্রদত্ত সমীকরণে বিকল্পগুলি প্রয়োগ করে এবং BODMAS নিয়ম ব্যবহার করে সমাধান করে পাই:
প্রদত্ত সমীকরণ: 248 ÷ 4 + 184 ÷ (4 × 6 – 2 × 8) = 77
বিকল্প 1) 8 এবং 4
বিনিময় করে পাই:
⇒ 248 ÷ 8 + 184 ÷ (4 × 6 – 2 × 4) = 77
⇒ 248 ÷ 8 + 184 ÷ (24 – 8) = 77
⇒ 248 ÷ 8 + 184 ÷ 16 = 77
⇒ 31 + 11.5 = 77
⇒ 42.5 ≠ 77
প্রদত্ত সমীকরণ: 248 ÷ 4 + 184 ÷ (4 × 6 – 2 × 8) = 77
বিকল্প 2) 184 এবং 77
বিনিময় করে পাই:
⇒ 248 ÷ 4 + 77 ÷ (4 × 6 – 2 × 8) = 184
⇒ 248 ÷ 4 + 77 ÷ (24 – 16) = 184
⇒ 248 ÷ 4 + 77 ÷ 8 = 184
⇒ 62 + 9.6 = 184
⇒ 71.6 ≠ 184
প্রদত্ত সমীকরণ: 248 ÷ 4 + 184 ÷ (4 × 6 – 2 × 8) = 77
বিকল্প 3) 184 এবং 248
বিনিময় করে পাই:
⇒ 184 ÷ 4 + 248 ÷ (4 × 6 – 2 × 8) = 77
⇒ 184 ÷ 4 + 248 ÷ (24 – 16) = 77
⇒ 184 ÷ 4 + 248 ÷ 8 = 77
⇒ 46 + 31 = 77
⇒ 77 = 77
প্রদত্ত সমীকরণ: 248 ÷ 4 + 184 ÷ (4 × 6 – 2 × 8) = 77
বিকল্প 4) 4 এবং 6
বিনিময় করে পাই:
⇒ 248 ÷ 6 + 184 ÷ (4 × 4 – 2 × 8) = 77
⇒ 248 ÷ 6 + 184 ÷ (16 – 16) = 77
⇒ 248 ÷ 6 + 184 ÷ 0 = 77
⇒ 41.3 + 0 = 77
⇒ 41.3 ≠ 77
সুতরাং, সঠিক উত্তর হল "বিকল্প 3"
