Answer 1

Answer:

23 and 1/3 days or 23 days 8 hours.

Step-by-step explanation:

$no. \: of \: machines = 28$

$no. \: of \: days \: required = 20 \: days$

$total \: work \: done \: = 28 \times 20 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 560$

Now,

$four \: machines \: are \: not \: working = \frac{560}{28 - 4} \\ = \frac{560}{24} \\ = 23 \frac{8}{24} \\ = 23 \frac{1}{3}$

Therefore, 23 and 1/3 days or 23 days 8 hours are required to make the same number of shirts if four machines are not working properly
