8 machines can do a piece of work in 10 days. How long will it take 16 machines to do the work?
مشینیں 10 دن میں ایک کام کر سکتی ہیں۔ 16 مشینوں کو کام کرنے میں کتنا وقت لگے گا؟
Answer: 05 days
Explanation
Let:
- M1 = Number of machines in the first case = 8
- D1 = Number of days taken in the first case = 10
- M2 = Number of machines in the second case = 16
- D2 = Number of days taken in the second case =?
The formula for inverse proportion is: M1 * D1 = M2 * D2
Substitute the values: 8 * 10 = 16 * D2 80 = 16 * D2
To find D2, divide both sides by 16: D2 = 80 / 16 D2 = 5
So, it will take 16 machines 5 days to do the work.
