Answer 1

Answer :-

$\huge\sf\boxed{25}$

Explanation :-

Given :

• No. of boys = 12
• No. of girls = 18
• Fraction of students absent on a certain day = 1/6

To find :

The number of students present

Solution :

Total number of students :-

= (No. of boys + No. of girls)

$\sf\rightarrow (12 + 18)$

$\sf\rightarrow 30$

Now, Fraction of students absent on that certain day = 1/6 of 30

$\sf\rightarrow \dfrac{1}{6} \times 30$

$\sf\rightarrow 5$

Therefore, No. of students present :-

= (Total no. of students - No. of students absent on that certain day)

$\sf\rightarrow (30 - 5)$

$\sf\rightarrow 5$

Hence, the number of students present on the certain day were 25
