Correct Answer: 36 + 6 – 3 × 2 = 20
Solution : Given: + means ÷, × means +, – means ×, and ÷ means –
Let's check the options – First option: 36 × 6 + 3 – 2 < 20 = 36 + 6 ÷ 3 × 2 = 36 + 2 × 2 = 36 + 4 = 40 > 20; L.H.S. is not smaller than R.H.S. Second option: 36 × 6 + 3 × 2 = 20 = 36 + 6 ÷ 3 + 2 = 36 + 2 + 2 = 40 ≠ 20; L.H.S. ≠ R.H.S. Third option: 36 + 6 × 3 + 2 = 20 = 36 ÷ 6 + 3 ÷ 2 = 6 + 1.5 = 7.5 ≠ 20; L.H.S. ≠ R.H.S. Fourth option: 36 + 6 – 3 × 2 = 20 = 36 ÷ 6 × 3 + 2 = 20 = 6 × 3 + 2 = 18 + 2 = 20; L.H.S. = R.H.S.
So, only the fourth option satisfies the equation. Hence, the fourth option is correct.
