Answer 2

800 workers need to be appointed.

Step-by-step explanation:

Since we have given that

Number of workers = 300

Number of days = 16

If 25% of work is to be done in 15 days, number of workers needs to be appointed be 'x'.

According to question,

$300\times 16=\dfrac{x\times 15}{\dfrac{1}{4}}\\\\300\times 16=x\times 15\times 4\\\\x=800$

Hence, 800 workers need to be appointed.
