Answer to Problem 19PTTS

The number of students participated last year is 360 .

Explanation of Solution

Given information: The number of students participating in a math competition increased by 22% from last year. If 427 students participated this year, how many students participated last year?

Calculation:

The number of students participated this year is 427 ......(1)

The increased rate of one year is 22% .

Let, The number of students participated last year is x .

Since, The increase rate is 22% than the number of students increased =22% of x .

Where,

  22% of x = 22100×x=0.22x

Now, The total number of students participated this year =x+0.22x

  =1.22x ......(2)

Let’s find the value of x from the equation (1) and (2) ,

  1.22x=427x=4271.22x=350

Hence, The number of students participated last year is 360 .
