Answer:
Case1:
Men : 30
Work : 1
Time (day×hr): 56×6 = 336 hr.
Case2:
Men : let it be m men.
Work: 1
Time: 45×7 = 315 hr.
Work being constant in both cases, men and time are in inverse proportion i.e, more men take less time.
Product of men and time is constant in both cases.
Therefore, 30×336=m×315
Or, 30×336/315 = m
Or, m = 32.
Hence, required number of men is 32.

Answer:12.8
Step-by-step explanation:
Answer: 1.30 every km
Step-by-step explanation:
to find the speed per km, you do 41 divided by 31.
41/31= 1.30 per km (rounded)
Cross multiply.
14/12=x/18
14 x 18 = 252
252/12= 21
so x=21
Your question is a bit unclear, but if you mean which lines are parallel to this one then I have an answer.
1/2*4=2 so this line would be y=2 which means it is a horizontal line. Therefore, any other horizontal line would be parallel to it. So just pick a value for Y to equal and that will be your answer.
ie. y=7
