If ‘+’ stands for ‘multiplication’, ‘<’ stands for ‘division’, ‘÷’ stands for ‘subtraction’, ‘–‘ stand for ‘addition’ and ‘×’ stands for ‘greater’ than. Identify which expression is correct?

  • A.20 – 40 + 4 + 8 < 2 × 26
  • B.20 × 8 + 15 < 5 ÷ 9 - 8
  • C.20 < 2 + 10 ÷ 4 – 6 × 100
  • D.20 < 5 + 25 ÷ 10 – 2 × 96

Answer: C

20 ÷ 2 × 10 – 4 + 6 > 100

= 10 × 10 – 4 + 6 > 100

= 106 – 4 > 100

=   102 > 100.
