If '∞' means '×', 'π' means '÷', 'Σ' means '+', and 'Δ' means '-', find the value of 12∞8π4Δ10Σ6.
Show answer & explanation
Correct answer: D
Explanation
Given symbol meanings:
• '∞' means '×'
• 'π' means '÷'
• 'Σ' means '+'
• 'Δ' means '-'
Given expression:
12 ∞ 8 π 4 Δ 10 Σ 6
Substitute the respective operators:
= 12 × 8 ÷ 4 − 10 + 6
Applying the BODMAS rule:
• Division: 8 ÷ 4 = 2
= 12 × 2 − 10 + 6
• Multiplication: 12 × 2 = 24
= 24 − 10 + 6
• Addition & Subtraction:
= (24 + 6) − 10
= 30 − 10
= 20
Hence, the correct option is (D).
