A dairy farm has 4 cows. Each cow gives 7 L on Monday, 6 L on Tuesday, 8 L on Wednesday, 7 L on Thursday, and 5 L on Friday. How many liters of milk are produced by all cows in this week?
Answer
132 liters
The correct answer is 132 liters — So the farm produces 132 liters of milk in that week.
Step-by-step solution
- Sum the daily milk production for one cow: 7+6+8+7+5 = 33 L per week.
- Multiply by the 4 cows: 33 L × 4 = 132 L.
- So the farm produces 132 liters of milk in that week.
Common mistake: Mis‑adding daily amounts or forgetting to multiply by number of cows
Concept tested: Multiplication & addition of milk production
