If '↑' means '+', '↓' means '-', '→' means '÷', and '←' means '×', then find the value of (25 ← 4) ↓ 50 ↑ (60 → 5).
Show answer & explanation
Correct answer: D
Explanation
Given symbol meanings:
• '↑' means '+'
• '↓' means '−'
• '→' means '÷'
• '←' means '×'
Given expression: (25 ← 4) ↓ 50 ↑ (60 → 5)
Replacing the symbols with mathematical operators:
= (25 × 4) − 50 + (60 ÷ 5)
Using the BODMAS rule:
= 100 − 50 + 12
= 50 + 12
= 62
Therefore, the correct option is (D).
