4 workers get paid = 160,000 for 5 days
Hence,
1 worker gets paid = [tex] \frac{160,000}{4} = 40,000[/tex] for 5 days.
From here we can find out how much 1 worker is paid for 1 day by dividing by 5;
1 worker gets paid = [tex] \frac{40,000}{5} = 8,000[/tex] for 1 day.
Therefore,
5 workers get paid = [tex]8,000 * 5 = 40, 000[/tex] for 1 day.
