Question

A ship going on a long journey had 35 days of
food for 600 passengers. If the food lasted for
only 30 days, how many passengers were there
on the ship?​

Answer 1

A ship is going on a long journey,

1) 600 passengers can finish food in 35 days.

2) 1 passenger can finish the same food in 600*35 days

3) X passengers can finish the food in (600*35)/X days

4) If (600*35)/X = 30, we have X= 700.

5) Therefore, There were 700 passengers on the ship who finished the food in 30 days.
