Question

If the average weight of the men in a group is 60 kg and that of the women is 72 kg. If the

average weight of the class is 68 kg, what is the ratio of men to women in the class?​

Answer 1

Step-by-step explanation:

Let the num of men is x and the number of women is y

68(x+y)=60x+72y

68x-60x=72y-68y

8x=4y

x/y=4/8=1/2

the ratio of men to women in the class 1:2
