Detailed Solution
Download Solution PDFপ্রদত্ত সমীকরণ: 104 ÷ 8 – 24 × 5 + 9 = 34
এখন, চিহ্ন বিনিময় করার পর
- বিকল্প - (1) : + এবং ÷
104 ÷ 8 – 24 × 5 + 9 = 34 ⇒ 104 + 8 – 24 × 5 ÷ 9 = 34
104 + 8 – 24 × 5 ÷ 9 = 34
104 + 8 – 24 × 0.5 5 = 34
104 + 8 – 13.2 = 34
112 – 13.2 = 34
98.8 ≠ 34 (LHS ≠ RHS)
- বিকল্প - (2) : – এবং +
104 ÷ 8 – 24 × 5 + 9 = 34 ⇒ 104 ÷ 8 + 24 × 5 - 9 = 34
104 ÷ 8 + 24 × 5 - 9 = 34
13 + 24 × 5 - 9 = 34
13 + 120 - 9 = 34
133 - 9 = 34
124 ≠ 34 (LHS ≠ RHS)
- বিকল্প - (3) : + এবং ×
104 ÷ 8 – 24 × 5 + 9 = 34⇒ 104 ÷ 8 – 24 + 5 × 9 = 34
104 ÷ 8 – 24 + 5 × 9 = 34
13 – 24 + 5 × 9 = 34
13 + 45 - 24 = 34
58 - 24 = 34
34 = 34 (LHS = RHS)
- বিকল্প - (4) : ÷ এবং ×
104 ÷ 8 – 24 × 5 + 9 = 34 ⇒ 104 × 8 – 24 ÷ 5 + 9 = 34
104 × 8 – 24 ÷ 5 + 9 = 34
104 × 8 – 4.8 + 9 = 34
832 + 9 - 4.8 = 34
841 - 4.8 = 34
836.2 ≠ 34 (LHS ≠ RHS)
সুতরাং, সঠিক উত্তর হল "বিকল্প - (3)"
