In a group of men, women, and children, the ratio of the number of women to the number of children is 4:1. What is the total number of people in the group?
(1) The ratio of the number of children to the number of men in the group is 3:5.
(2) The number of women in the group is between 30 and 40.
In a group containing men, women and children.
Women : Children = 4:1 = 4x : x
We need to find the total number of people.
Statement 1:
(1) The ratio of the number of children to the number of men in the group is 3:5.
we know that Women : Children = 4x : x
Children to men = 3x : 5x
Men : Women : Children = 5x : 12x : 3x
Total = 5x + 12x + 3x = 20x
Hence,
Insufficient. Statement 2:
(2) The number of women in the group is between 30 and 40.
As per the question : Women = 4x
30 < 4x < 40
4x can be 4*8 = 32 OR 4*9 = 36
so, x can take values 8 or 9.
Hence,
Insufficient.
Combining both Statements 1 and 2, we get
Men : Women : Children = 5x : 12x : 3x
and, 30 < Women < 40
30 < 12x <40
Thus, 12x = 12*3 = 36 is the only possible value.
Thus, x can take the value
3 ONLY.
Total = 5x + 12x + 3x = 20x = 20*3 = 60
So, the total number of people =
60 Hence,
Sufficient Option C
