Detailed Solution
Download Solution PDFআমরা প্রদত্ত সমীকরণে বিকল্পগুলি প্রয়োগ করি এবং BODMAS নিয়ম ব্যবহার করে সমাধান করি:
বিকল্প 1) +, ÷, ×, -
5 + 15 ÷ 320 × 2 - 45 = 190
5 + 0.04 × 2 - 45 = 190
5 + 0.08 - 45 = 190
5.08 - 45 = 190
-39.92 ≠ 190
বিকল্প 2) ×, +, ÷, -
5 × 15 + 320 ÷ 2 - 45 = 190
5 × 15 + 160 - 45 = 190
75 + 160 - 45 = 190
235 - 45 = 190
190 = 190
বিকল্প 3) +, ×, ÷, -
5 + 15 × 320 ÷ 2 - 45 = 190
5 + 15 × 160 - 45 = 190
5 + 2400 - 45 = 190
2405 - 45 = 190
2360 ≠ 190
বিকল্প 4) ×, ÷, -, +
5 × 15 ÷ 320 - 2 + 45 = 190
5 × 0.04 - 2 + 45 = 190
0.2 - 2 + 45 = 190
45.2 - 2 = 190
43.2 ≠ 190
সুতরাং, সঠিক উত্তর হল বিকল্প 2)
