The ages of a mother and daughter are in ratio 8:5.if the daughters age now is 15, what was the mother's age 6 yrs ago
The question is quite stupid.
m = present mother's age
d = present daugher's age
The ages of a mother and daughter are in ratio 8:5 means:
m / d = 8 / 5
Replace d by 15 in this equation.
m / 15 = 8 / 5
Cross multiply.
m • 5 = 15 • 8
5 m = 120
m = 120 / 5 = 24
Mother present age = 24
Daughter present age = 15
This means, the mother gave birth to her daughter when she was 9 years old???
Mother's age 6 yrs ago = 24 - 6 = 18
THE QUESTION IS QUITE STUPID.
THE QUESTION IS QUITE S T U P I D.
What idiot edited this page so the word S T U P I D is banned?
I D I O T is also banned.
so is B O S N I A N ...
Bosnian is less I D I O T than the admins of this sie, including oobleck.
Stop fighting. Its not helpful. It doesn't matter okay?
To find the mother's age 6 years ago, we need to determine the ratio between the daughter's age now and 6 years ago.
Let's set up the ratios:
Current ratio of mother's age to daughter's age is 8:5.
Let's represent the daughter's current age as x.
Since the current daughter's age is 15, we have:
5 (daughter's age now) = x
So, x = 15.
Now, let's find the mother's current age using the ratio:
8 (mother's age now) = 8/5 (daughter's age now)
8 (mother's age now) = 8/5 * 15
8 (mother's age now) = 120/5
8 (mother's age now) = 24
So, the mother's current age is 24.
Now, to find the mother's age 6 years ago, we deduct 6 from her current age:
Mother's age 6 years ago = 24 - 6 = 18
Therefore, the mother's age 6 years ago was 18.
