Question

The number of students was increased by 30% and it became 455 what was the previous number of students?

Answer 1

Answer:

342 students

Step-by-step explanation:

let the previous no. of students be x.

Therefore x + 30% of x = 445

445 = x + (30x / 100)

445 = 130x / 100

44500 = 130x

x = 44500 / 130 = 4450 / 13 = 342 students.
