Detailed Solution
Download Solution PDFপ্রদত্ত বিবৃতি: 77 ÷ 7 − 2 x 3 + 3 = 4
প্রশ্ন অনুসারে , সংখ্যাগুলির স্থান বিনিময় করার পরে :
সুতরাং,
- বিকল্প - (1): 3 এবং 77
77 ÷ 7 − 2 x 3 + 3 = 4 ⇒ 3 ÷ 7 − 2 x 77 + 3 = 4
0.42 − 2 x 77 + 3 = 4
0.42 + 3 - 154 = 4
3.42 - 154 = 4
-150.58 ≠ 4 (বামপক্ষ ≠ ডানপক্ষ)
- বিকল্প - (2): 3 এবং 7
77 ÷ 7 − 2 x 3 + 3 = 4 ⇒ 77 ÷ 3 − 2 x 7 + 3 = 4
25.67 − 2 x 7 + 3 = 4
25.67 + 3 - 14 = 4
28.67 - 14 = 4
14.67 ≠ 4 (বামপক্ষ ≠ ডানপক্ষ)
- বিকল্প - (3): 2 এবং 4
77 ÷ 7 − 2 x 3 + 3 = 4 ⇒ 77 ÷ 7 − 4 x 3 + 3 = 2
11 − 4 x 3 + 3 = 2
11 + 3 - 12 = 2
14 - 12 = 2
2 = 2 (বামপক্ষ = ডানপক্ষ)
- বিকল্প - (4): 2 এবং 7
77 ÷ 7 − 2 x 3 + 3 = 4 ⇒ 77 ÷ 2 − 7 x 3 + 3 = 4
38.5 − 7 x 3 + 3 = 4
38.5 + 3 - 21 = 4
35.5 - 21 = 4
14.5 ≠ 4 (বামপক্ষ ≠ ডানপক্ষ)
