Step-by-step explanation:

{\large{\bf{\purple{Question :}}}} \\

1/6 of the class students are above average 1/4 are average are rest are below average if there are 48 student in all how many students are below average in the class.

{\large{\bf{\purple{Solution :}}}} \\

Number of students in the class are above average :-

{\bold{\rm{:  \: ⟹  \:  \:  \:  \:  \:  \: \frac{1}{6}}}}  \\  \\

Number of students in the class are average :-

{\bold{\rm{: \:  ⟹ \:  \:  \:   \: \:  \:  \frac{1}{4}}}}  \\  \\

Students in the class are below average :-

{\bold{\rm{:  \: ⟹  \:  \:  \:  \:  \:  \: 1  \: - \:  \Big(\frac{1}{6}  \: - \:  \frac{1}{4}\Big)}}}  \\  \\

{\bold{\rm{:  \: ⟹  \:  \:  \:  \:  \:  \: 1 \:  - \:  \Big(\frac{2  \: + \:  3}{12}\Big)}}}  \\  \\

{\bold{\rm{: \:  ⟹ \:  \:  \:  \:  \:  \:  1 - \:  \Big(\frac{5}{12}\Big)}}}  \\  \\

{\bold{\rm{:  \: ⟹  \:  \:  \:  \:  \: \frac{12 \:  -  \: 5}{12}}}}  \\  \\

{\bold{\rm{:  \: ⟹ \:  \:  \:  \:  \:  \:  \frac{7}{12}}}}  \\  \\

So, 7/12th students are below average

The number of students in the class = 48

Then, Number of students below average :-

{\bold{\rm{: \:  ⟹ \:  \:  \:  \:  \:  \:  \frac{7}{12} \:  × \:  48}}}  \\  \\

{\bold{\rm{:  \: ⟹ \:  \:  \:  \:  \:  \:  7 \:  × \:  4}}}  \\  \\

{\bold{\rm{: \:  ⟹  \:  \:  \:  \:  \:  \: 28}}}  \\  \\

∴ The number of students in the class are below average are 28.

Answer:

{\underline {\bf {QUESTION}}}

1/6 of the class students are above average 1/4 are average are rest are below average if there are 48 student in all how many students are below average in the class?

 \mathcal {ANSWER}

Number of students in the class are above average = 1/6

Number of students in the class are average = 1/4

Number of students in the class are below average = 1 – ((1/6) + (¼))

= 1 – ((2 + 3)/12)

= 1 – (5/12)

= (12 – 5)/12

= 7/12 Students

So, the number of students in the class = 48.

Then,

Number of students below average

= (7/12) × 48

= (7/1) × 4 = 28 students

∴The number of students in the class are below average are 28.
