Question

A camp has provisions for 60 persons for 18 days ; in how many days will the provision finish off if the the strength of persons is increased to 72

Answer 1

Answer:

15 days

Step-by-step explanation:

Here

No. of Persons      60             72

Days                      18              x₁

Since number of persons are increasing and provision is same, it will consumed before 18 days, means one quantity is increasing and one quantity is decreasing. It is a case of Inverse Proportion, according to which

60 × 18 = 72 × x₁

x₁ = (60 × 18)/72

x₁ = 15

∴ Provision will finish in 15 days
