If > denotes '+', < denotes '-', + denotes '÷' , - denotes '=' , '×' denotes '>' and = denotes '<' , choose the correct statement from the following:

  1. 14 + 7 > 3 = 6 + 3 > 2

  2. 6 + 3 > 8 = 4 + 2 < 1

  3. 9 < 6 + 3 = 7 > 4

  4. 4 > 6 + 2 × 32 + 4 < 1

Show answer & explanation

Answer: (C) 9 < 6 + 3 = 7 > 4

Explanation

Decoding option 3: 9 − 6 ÷ 3 < 7 + 4, i.e. 9 − 2 = 7 < 11, which is true. For example option 1 becomes 14 ÷ 7 + 3 < 6 ÷ 3 + 2, i.e. 5 < 4, which is false.
