Quest Statement says : w:m:c <=> 5:2:7
1) 1st statement says W+C is 12
we know W:C <=> 5:7
That clearly means w=5 and c=7 hence m=2 and total nbr of people 14 .... SUFFICIENT
2) 2nd statement says Men < 4
Which means that Men could be 3 or 2 or 1
It cant be three since the common multiplier will be 1.5 and 5*1.5 is a decimal figure and number of women cant be in decimals
It cant be 1 since the common multiplier will be 0.5 and 5*0,5 is is a decimal figure and number of women cant be in decimals
So we left with 2 and that tells common multiplier is 1 thus number of w / c and m = 5+2+7 = 14 ... SUFFICIENT
hence answer is D
The ratio of the number of women to the number of men to the number of children in a room is
5:2:7, respectively. What is the total number of people in the room?
