What is the number of agricultural workers who had enjoyed world cup matches on TV?​

Answer 1

Answer:

Answer: There are 260 agricultural workers who had enjoyed world cup matches on TV.

Step-by-step explanation:

Since we have given that

Number of persons = 100

Percent who were industrial workers = 25%

So, the number of industrial workers is given by

\begin{gathered}0.25\times 1000\\\\=250\end{gathered}

0.25×1000

=250

Percent who were agricultural workers = 75%

So, the number of agricultural workers is given by

\begin{gathered}0.75\times 1000\\\\=750\end{gathered}

0.75×1000

=750

Number of persons enjoyed world cup matches = 300

So, the number of persons who did not enjoy world cup matches = 1000 - 300 =700

Percent of the people who had not watched world cup matches are industrial workers = 30%

Number of people who are industrial workers but do not watch world cup matches is given by

\begin{gathered}0.3\times 700\\\\=210\end{gathered}

0.3×700

=210

Number of industrial workers who enjoy world cup matches is given by

250-210=40250−210=40

So, the number of agricultural workers who had enjoyed world cup matches on Tv is given by

\begin{gathered}300-40\\\\=260\end{gathered}

300−40

=260

Hence, there are 260 agricultural workers who had enjoyed world cup matches on TV.
