Question

4.If 15 workers can build a wall in 48
hrs,how many workers will be
required to do the same work in
30hrs.​

Answer 1

Step-by-step explanation:

hours :48

workers : 15

so h×w = 720.... (1)

48×15 = 720

so in equation second

h×w = 720

30×w = 720

w= 720/30

w= 24

hence 24 workers are required
