Answer 2

Answer:

24 Labors

Step-by-step explanation:

$\left[\begin{array}{ccc}Labours&15&x\\Hours&48&30\\\end{array}\right]$

Since to finish the work earlier( in 30 hours) we need more laborers. Means One quantity is decreasing and one is increasing. Its a case of Inverse proportion.

∴ 15 × 48 = x × 30

x = 24

Hence 24 laborers required to finish the job in 30 hours.
