Question

the ratio of the mothers and daughters is 9:4 after 6 years the ratio would be 2:1 how many years old should the mother at the age of time of birth of her daughter hi in​

Answer 1

Answer:

20

Step-by-step explanation:

Let mother’s age be 9x and daughter’s age be 5x…

So acc to first condition

9x X 5x = 1125

45x^2 = 1125

x^2 = 25

x = 5

So mother's age is 9 x 5 = 45 and daughter's age is 5 x 5 = 25.

45 - 25 = 20

Therefore the mother was 20 at time of birth

Answer 2

Answer:

9x+6/4x+6=2/1

9x+6=2(4x+6)

9x+6=8x+12

9x-8x=12-6

x=6

so now mother age =9x=9×6=54

daughter age =4x=4×6=24

the mother at the age of time of birth of her daughter,

54-24=30

so mother age that time 30.
