Correct Answer - Option 5 : 16.66%
Calculation:
Let the initial cost of the fresh strawberries = 100
Packaging cost = 20
∴ Initial total cost = 120
After increasing in cost of fresh strawberries by 30%, then cost of fresh strawberries = 130
Cost of packaging goes down by 50%, then the cost of packaging = 10
∴ total cost after changes = 130 + 10
⇒ 140
∴ increased Cost = 140 – 120
⇒ 20
∴ % increased = 20/120 × 100
⇒ 16.66%
∴ the percentage change of the cost of packed strawberries is 16.66%.
