Question

For an online educational clip, 80 percent of the first 240 viewers voted “like” for the clip. If all of the next 80 viewers voted “like” for the clip, what percent of all these viewers voted “like”?

Answer 1

Answer: There is 85% of all these viewers voted "like".

Step-by-step explanation:

Since we have given that

Number of first viewers  = 240

Percentage of first viewers who voted "like" for the clip = 80%

Number of people who voted "like" for the clip =

$\dfrac{80}{100}\times 240\\\\=0.8\times 240\\\\=192$

Number of next viewers = 80

total number of viewers = 240+80 = 320

Number of viewers who voted "like" for the clip = 80

Total number of viewers who voted "like" for the clip = 192+80=272

So, overall percentage of viewers voted "like" is given by

$\dfrac{272}{320}\times 100\\\\=85\%$

Hence, there is 85% of all these viewers voted "like".
