If ‘+’ stands for ‘multiplication’, ‘<’ stands for ‘division’, ‘÷’ stands for ‘subtraction’, ‘-‘ stand for ‘addition’ and ‘×’ stands for ‘greater’ than. Identify which expression is correct?
Answer: C
Correct answer: 20 < 2 + 10 ÷ 4 – 6 × 100
Substituting gives \( 20 \div 2 \times 10 - 4 + 6 \) on the left, and the final symbol means greater than. Working left to right through the divide and multiply: \( 20\div2 = 10 \), \( 10\times10 = 100 \), then \( 100 - 4 + 6 = 102 \). Since 102 exceeds 100 the statement holds.
