In a camp, 95 kg food is sufficient for 5 persons. Find the quantity of food required for 23 persons.
NNADVOKAT [17]
95/5= 19 (the rate; each person needs 19 kg of food)

So,

You need to multiply that by 23 to get the amount you need for 23 people.

19*23= 437 kg

437 kg is sufficient for 23 people.
