প্রশ্ন অনুসারে, * চিহ্নগুলি প্রতিস্থাপন করে:
অতএব,
- বিকল্প - (1) : ÷, ×, +, =
50 ÷ 10 × 20 + 5 = 105
5 × 20 + 5 = 105
100 + 5 = 105
105 = 105 (বাম পক্ষ = ডান পক্ষ)
- বিকল্প - (2) : ×, -, +, =
50 × 10 - 20 + 5 = 105
500 + 5 - 20 = 105
505 - 20 = 105
485 ≠ 105 (বাম পক্ষ ≠ ডান পক্ষ)
- বিকল্প - (3) : ÷, ×, -, =
50 ÷ 10 × 20 - 5 = 105
5 × 20 - 5 = 105
100 - 5 = 105
95 ≠ 105 (বাম পক্ষ ≠ ডান পক্ষ)
- বিকল্প - (4) : ×, ÷, +, =
50 × 10 ÷ 20 + 5 = 105
50 × 0.5 + 5 = 105
25 + 5 = 105
30 ≠ 105 (বাম পক্ষ ≠ ডান পক্ষ)
সুতরাং, "বিকল্প - (1)" হল সঠিক উত্তর।
