Question

On a rainy day 48% of the students were present in school if the number of absentees on that day was 156 find the total strength of the school

Answer 1

GIVEN :

• Percent of students present in school = 48%

• Number of absentees on that day = 156

TO FIND :

• Total strength of students in school = ?

STEP-BY-STEP EXPLANATION :

Let us consider / assume 'The total strength of students in school = ' X '

NOW,

$\frac{x - 156}{x} \times 100 = 48\%$

$(x - 156) \times 100 = 48x$

$100x - 15600 = 48x$

$- 15600 = (48 - 100x)$

$- 52 = 15600$

$x = \frac{ - 15600}{ - 52} = 300$

Hence, Total strength of Students in school = 300 Students
