1.	In a camp, there is enough flour for 300 persons for 42 days. How long will the flour last if 20 more persons join the camp?
Answer» ∵For 300 persons flour is enough for 42 days. ∴ For 1 person’s flour enough = 300 × 42 = 1260 days. Now, 20 more persons join the camp. So, total persons = 300 + 20 = 320 ∴ For 320 persons flour enough = 12600/320 = 3/8 days

In a camp, there is enough flour for 300 persons for 42 days. How long will the flour last if 20 more persons join the camp?

Answer»

∵For 300 persons flour is enough for 42 days.

∴ For 1 person’s flour enough = 300 × 42 = 1260 days.

Now, 20 more persons join the camp.

So, total persons = 300 + 20 = 320

∴ For 320 persons flour enough = 12600/320 = 3/8 days
