Question

. 400 men have provisions for 23 weeks. They are joined by 60 men. How long will the provisions last?​

Answer 1

Answer:

400 men have provisions for = 23 weeks

1 man will have provisions for = 23\times400\ weeks

And 400 + 60 = 460 men will have provisions for = \frac{23\times400}{460}=20\ weeks
