Question

a party attentend by a total of 60 persons if the ratio of men and women is 3:2how many more men ist just join the party so that the ratio becomes 7:3​

Answer 1

Let the number of men and women be 3x and 2x.

3x+2x=60

5x=60

x = 12

Let no of more men = y

36+y =  7

24         3

3(36+y) = 7*24

108+3y = 168

3y =60

y = 20.

.: 20 more men came in.
