Question

Students of Class VI were asked about their favourite TV channel . The results were shown in the following bar graph. How many students like the channel which is $2\frac{1}{2}$ times the ESPN?

Answer 1

Step 1: Observing the given graph

According to the bar graph given,

Number of students watch Zee TV$=60$

Number of students watch Discovery$=100$

Number of students watch ESPN$=40$

Number of students watch Ten sports$=70$

Number of students watch Aaj Tak$=30$

Step 2: Finding $2\frac{1}{2}$ times the ESPN

$2\frac{1}{2}$ times the ESPN $=2\frac{1}{2}\times 40$…….(Number of students watch ESPN$=40$)

$$\begin{gathered} =\frac{5}{2}\times 40 \\ =5\times 20 \\ =100 \end{gathered}$$

so, Only Discovery channel is watched and liked by $100$students.

Hence, Discovery channel is $2\frac{1}{2}$ times the ESPN .
