A total of 295 student and teacher desks were purchased. How many original students desks were there before the purchase was made?

Answer 1

The number of original students desk were there before the purchase is 980 .

Explanation:

Given as :

The total number of students and teachers new desks to be purchased = 295

The number of teacher's new desk to be purchased = 50

So , The number of student's new desk to be purchased = 295 - 50 = 245

The number of student's new desk to be replaced this year =
`(1)/(4)` of the original students desk

Let The number of original students desk were there before the purchase = x

Or, According to question

`(1)/(4)` of x = 245

Or, x = 245 × 4

∴ x = 980

Hence The number of original students desk were there before the purchase is 980 . Answer
