Question

12. A garrison of 120 men has provision for 30 days. At the end of five days, five more
men joined them. How many days can they sustain on the remaining provision?
​

Answer 1

Answer:

120 men consume the remaining  provisions after 5 days  in =(30-5)=25 days

(I men will consume them in a longer period of time)

Hence 1 men will consume it in=25x120

125 men will consume the provisions =25x120/ 125

                                                          =24 days
