Step-by-step explanation:
9 crew members complete a job in 3 months
Number of crew members is inversely proportion to construction time :
Let :
Crew members = m
Construction time = t
m α 1 /t
m = k/t
m = 9 ; t = 3
9 = k /3
k = 27
If t = 1 (one month)
m =?
m = k/t
m = 27 / 1
Hence;
m = 27 * 1
m = 27 workers
Here is your answer
B. (12,30)
REASON:
Given,
.......(i)
.......(ii)
Putting the value of y from eq.i in eq.ii we get




Putting x=12 in eq.i we get



So,

Hence answer is (12,30) in which x=12 and y=30
