Let 1 apple-unit be the smallest. Pears = 3 apples = 3 units. Oranges = twice the pears = 6 units = 258.

[[model:questions/solutions/q3197.png]]

• Oranges = 6 units → 258
• 1 unit → 258 ÷ 6 = 43 (apples)
• Pears = 3 units → 129
• Total = 43 + 129 + 258 = 430

Altogether there are 430 fruits.
Check: apples 43 + pears 129 + oranges 258 = 430. ✓
