Answer:
ans is 63 days
Step-by-step explanation:
No. of men at the beginning =450
No. of men arrived after 10 days =50
Total Number of mens after 10 days =450+50=500
Total . of days =80
After 10 days, period =70 days
After 10 days, there will be 500 mens
Let x be the no. of days till which the food remains
∴450:500=70:x
By inverse proportion,
500:450=70:x
⟹
450
500
=
x
70
⟹x=
500
70×450
⟹x=63
Hence, till 63 days, the remaining food lasts at the same rate.
