many students are required so that work finishes in two days? ​

Answer 1

Answer:15 students completes the work in 2 days.

Step-by-step explanation:

Given Problem is of inverse proportion as no of student increase result in decrease of day to finish the work.

No of Student required to a work in 3 days = 10

let No of Student required to a work in 2 days = x

Condition for inverse proportion is given by,

10 × 3 = x × 2

30 = x × 2

x = 15

Therefore, 15 students completes the work in 2 days.
