Question

A camp has sufficient provision for 120 soldiers. If after 60 days, 40 soldiers were deputed elsewhere, how long will the remaining provision last for the remaining soldiers
​

Answer 1

Answer:

120 days is the correct answer

Answer 2

My abuelita always said: “Where one eats, two can eat”. So, according to her, I believe the food will last for 60 days at least. Maybe twice that.

But, if you apply simple arithmetic here:

120s * 60d = 7,200 daily rations

120s + 40s = 160 soldiers

7,200r / 160s = 45 days
