Detailed Solution
Download Solution PDF1. ÷, +, −, ×, =
150 ÷ 3 + 10 - 2 × 7 = 46
⇒ 50 + 10 - 14 = 46
⇒ 60 - 14 = 46
⇒ 46 = 46
2. −, ×, +, ÷, =
150 - 3 × 10 + 2 ÷ 7 = 46
⇒ 150 - 30 + 0.28 = 46
⇒ 150.28 - 30 = 46
⇒ 120.28 ≠ 46
3. +, −, ÷, ×, =
150 + 3 - 10 ÷ 2 × 7 = 46
⇒ 150 + 3 - 5 × 7 = 46
⇒ 150 + 3 - 35 = 46
⇒ 153 - 35 = 46
⇒ 118 ≠ 46
4. ×, +, ÷, −, =
150 × 3 + 10 ÷ 2 - 7 = 46
⇒ 450 + 5 - 7 = 46
⇒ 455 - 7 = 46
⇒ 448 ≠ 46
Hence, '÷, +, −, ×, =' is the correct answer.
