Given that 1000 soldiers have enough food for 180 days.
Hence After 20 days, the remaining food is sufficient for 180 - 20 = 160 days.
Given Remaining soldiers after 20 days = 1000 + 600 = 1600.
Let the remaining food be x.
1000 : 1600 :: x : 160
1000 * 160 = 1600x
160000 = 1600x
x = 100 days.
The remaining food lasts for 100 days.
Hence After 20 days, the remaining food is sufficient for 180 - 20 = 160 days.
Given Remaining soldiers after 20 days = 1000 + 600 = 1600.
Let the remaining food be x.
1000 : 1600 :: x : 160
1000 * 160 = 1600x
160000 = 1600x
x = 100 days.
The remaining food lasts for 100 days.

So sidhart ,the ration for 1000 soldiers is already given as 180 days....
Yes
....so why it is asumed as "x"
That is for the remaining ration
Means tough 1000 soldier's ration is 180 yet it is holded as "x"
But 180 is already given....
Let the remaining ration food is sufficient for 1000 soldiers for x days.
oh .....that's the point to be understood
