Question

in a camp there is enough food to feed certain number of people for 50 days if 30 more people join the camp after 10 days the food will last for 25 days how many people were earlier present in the camp​

Answer 1

To understand in an easier way

Let us assume that 100 soldiers can eat ration food(x) in 10 days

So for one day the food that they eaten is x/10

So for two days 2*(x/10)=x/5

So remaining food is x-(x/5)=4x/5

Let this food will be eat by 160 soldiers in ‘d’ days

If one soldier can eat 1/(10*100) th food per day then for

160 soldiers and ‘d’ days =160*d*1/(10*100)=d*4/25 th of food

This must be equal to remaining 4x/5 food

Therefore d*4/25=4/5=> d=5 days
