Download Solution PDFপ্রতিটি বিকল্প একে একে পরীক্ষা করি:
প্রদত্ত সমীকরণ: 15 × 5 ÷ 6 + 10 - 2 = 10
1) 2 এবং 5
15 × 2 ÷ 6 + 10 - 5 = 10
= 15 × 2/6 + 10 - 5
= 5 + 10 - 5
= 15 - 5
= 10
= 10 = ডানপক্ষ
2) 2 এবং 6
15 × 5 ÷ 2 + 10 - 6 = 10
= 15 × 2.5 + 10 - 6
= 37.5 + 10 - 6
= 47.5 - 6
= 41.5 ≠ ডানপক্ষ
3) 5 এবং 6
15 × 6 ÷ 5 + 10 - 2 = 10
= 15 × 6/5 + 10 - 2
= 18 + 10 - 2
= 28 - 2
= 26 ≠ ডানপক্ষ
4) 5 এবং 15
5 × 15 ÷ 6 + 10 - 2 = 10
= 5 × 15/6 + 10 - 2
= 12.5 + 10 - 2
= 22.5 - 2
= 20.5 ≠ ডানপক্ষ
সুতরাং, "2 এবং 5" সঠিক উত্তর।
