Answer:
b=7
Step-by-step explanation:
2(3b-1)= 40
divide both sides by 2
3b-1 = 20
then add 1 to each side
3b = 21
then divide both sides by 3
b = 7
then check 2(3*7-1) = 40

Let the number of men and the number of women in the beginning be x and y
Now,
Now, In 2nd case,
No. Of men=x-63 and no. Of women =y-12
Now,the ratio becomes
Now,we have, 2x=5y
Putting the value of Y=56 in 2x=5y,we get,

Hence, the number of men was 140 and the no. of women was 56
