Question

A ship has enough provision for 500 persons to last for 30days.if 100 more persons join the ship how long will the provision last

Answer 1

Total number of days will last the food = 30

Total number of persons = 500

more men join =100

=500+100

=600

More mens, less days,so this is a case of indirect variation

total no. of days 30 a

total no. of persons 500 600

30×500=a×600

30×500

600 = 25 days

so, the food will last for 25 days with 600 persons
