Question

The average age of a woman and her daughter is 16 years the proportion of their age is 7:00 ratio 1:00 so how much is the woman's age​

Answer 1

Answer:

28

Step-by-step explanation:

let daughter's age be x and woman's be y.

$\frac{x+y}{2}$=16   (1)

also $\frac{x}{y}= \frac{7}{1}$

x=7y

x+y=(16)(2) (from 1)

8y=32

y=4

woman's age = 32-4=28
