A $25$
B $24$
C $22$
D $28$

Solution & Step-by-step Explanation

Using the inverse proportionality formula M_{1} D_{1} = M_{2} D_{2} :Here, M_{1} = 15 workers, D_{1} = 48 hours, and D_{2} = 30 hours. Let M_{2} be the number of workers needed. 15 \times 48 = M_{2} \times 30 M_{2} = \frac{15 \times 48}{30} = \frac{48}{2} = 24 workers
