Question

Smitha went to school for 192 days in a year. If her attendance was 75%, find the total number of working days of the school in that year ​

Answer 1

Answer: The answer is 256 days

Step-by-step explanation:

Given, smitha went to school for 192 days in a year and her attendance was 75%

Let, the total number of working days is X

From the question, X 75% = 192

⇒ X × 75/100 = 192

⇒ X = 192 × 100/75

⇒ X = 256

∴The total number of working days of the school in that year is 256 days

Answer 2

Answer:

The total number of working days of the school in that year ​was $256$ days.      

Step-by-step explanation:

Given : Smitha attended school for days = $192$

          Her % attendance = $75$%

To find : Total number of working days of the school in that year ​?

Solution :

• It is given that Smitha attended school for days = $192$

                      Her % attendance = $75$%

                    Her % absence = $(100-75)$ = $25$%

• We have to find the total number of working days of the school in that year.
• Let, $x$ be the total number of working days of the school in that year.
• According to given data, the equation becomes,

          $x-25$% of $x=192$

           ∴ $x-\frac{25}{100} *x=192$

              ∴ $\frac{100x-25x}{100} =192$

                     ∴ $75x=192*100$

                     ∴ $75x=19200$        

                        ∴ $x=\frac{19200}{75}$

                        ∴ $x=256$

• ∴ The total number of working days of the school in that year ​was $256$ days.
