Question

If 15 workers can do a piece of work in 40 hours, in how many hours will 12 workers do it? ( A ) 40 ( B ) 30 ( C ) 35 ( D ) 50

Answer 1

Answer:

it is a proportion question, according to me :-

Step-by-step explanation:

no of workers-   15 | 12

time-                  40 | y2

put 2 downside of y

so

15/40 = 12/y2

3/8 = 12/y2

3*y2=8*12

Y2= 96/3

Y2= 32 32 hours is ur answer :D
