luda_lava [24]

Answer:

The number of original students desks were there in school before purchase was made is 980 .

Step-by-step explanation:

Given as :

The total number of new desks purchased including teacher and students = 295

The number of new desks purchased for students = $\frac{1}{4}$ of original students desks available

The number of new desks purchased for teachers = 50

Let The number of original students desks available before purchase = S

Now, According to question

∵ The total number of new desks purchased including teacher and students = 295

I.e The number of new desks purchased for students + The number of new desks purchased for teachers = 295

Or, $\frac{1}{4}$ of S + 50 = 295

Or, $\frac{1}{4}$ × S = 295 - 50

Or , $\frac{1}{4}$ × S = 245

∴ S = 245 × 4 = 980

So, original desks available for students = S = 980

Hence The number of original students desks were there in school before purchase was made is 980 . Answer
