in a group of 132 adult the ratio of man to woman is 3:8. if 30 more woman join the group what is the ratio of man and woman now? how to find it?​

Answer 1

Answer:

18:63

Step-by-step explanation:

Let the ratio be 3x:8x.

=> 3x + 8x = 132

=> 11x = 132

=> x = 12

Hence, number of men = 3 × 12 = 36

Number of women = 8 × 12 = 96

New number of women = 96+30 = 126

Hence, new ratio = 36:126 = 18:63
