  1. 9 + 9 > 9 = 9

  2. 9 < 7 + 7 = 6

  3. 7 # 7 > 77 + 7 = 7 # 7 > 1

  4. 7 > 7 < 7 + 7 = 14

Show answer & explanation

Answer: (D) 7 > 7 < 7 + 7 = 14

Explanation

Decoding option 4: 7 + 7 − 7 ÷ 7 < 14, i.e. 14 − 1 = 13 < 14, which is true. For example option 1 becomes 9 ÷ 9 + 9 < 9, i.e. 10 < 9, which is false.
