Question

The ratio of the numbers of men and women in a joint family is 9:8. If the number of men in the family is 18. Find the number of women in the family.

Answer 1

Answer:

No . of Women = 16

Step-by-step explanation:

Men : Women

9 : 8

No . of men = 18

18 : x

9 × 2 : 8 × 2

18 : 16

Answer 2

Answer:

5:2:7

let say common ratio is k

so 5k women 2k men and 7k children

total people in the room = 5k+2k+7k=14k

stmt1: 5k+7k = 12 => k = 1

therefore, no of people is 14*1 = 14

stmt2: fewer than 4 men means men can be 1 2 or 3

if no of men is 1 dat means k is 0.5 and women = 5 * 0.5 = 2.5 not possible

if no of men is 2 dat means k is 1 and women = 5 and children = 7 possible

if no of men is 3 dat means k is 1/3 and women = 5/3 not possible

since there is only one case so we can deduce no of people from this stmt too
