Detailed Solution
Download Solution PDFWe apply the options on the given equation & solve it using BODMAS rule:
Option 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
Option 2) ×, +, ÷, -
5 × 15 + 320 ÷ 2 - 45 = 190
5 × 15 + 160 - 45 = 190
75 + 160 - 45 = 190
235 - 45 = 190
190 = 190
Option 3) +, ×, ÷, -
5 + 15 × 320 ÷ 2 - 45 = 190
5 + 15 × 160 - 45 = 190
5 + 2400 - 45 = 190
2405 - 45 = 190
2360 ≠ 190
Option 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
Hence the correct answer is option 2)
