THE AGE OF A MOTHER AND DAUGHTER ARE IN RATIO 8:5 IF THE DAUGHTER AGE IS 15 WHAT WAS THE MOTHER AGE 6 YEARS AGO ?

8/5=m/15

5×m=15×8
5m= 120
m=120/5
m=24
6 years ago
=24-6
= 18 years

The ratio of their ages is constant. Therefore~mother/ daughter= 8/5=m/15.

M=16×8/5=24
Six years ago she was 24-6=18yrs. Answer.
Or
m/d=8/5
d=15, so m=24
m-6=24-6=18
m=18yrs. Final answer.✓✓✓

m/d = 8/5

d = 15, so m=24

so, what is m-6?

18

Well, if the daughter is 15 years old now and the ratio of their ages is 8:5, we can solve this mathematically.

Let's assume that 6 years ago, the daughter was x years old and the mother was y years old.

So, according to the given ratio, we can write the equation:

(x-6) / (y-6) = 8/5

Now, we can substitute the daughter's age 6 years ago, which is x-6 = 9 and solve for y:

(9) / (y-6) = 8/5

Cross multiplying gives us:

9 * 5 = 8 * (y-6)

45 = 8y - 48

8y = 93

y = 11.625

So, 6 years ago, the mother would have been approximately 11.625 years old.

Remember, this is just a calculation. If you want a humorous answer, let me know!

To find the mother's age 6 years ago, we need to determine the current age of the mother.

Given that the ratio of the mother's age to the daughter's age is 8:5, and the daughter's age is currently 15, we can set up the following proportion:

Mother's age / Daughter's age = 8 / 5

Substituting the given values, we get:

Mother's age / 15 = 8 / 5

To find the mother's age, we can cross-multiply and solve for her age:

5 * Mother's age = 15 * 8

5 * Mother's age = 120

Mother's age = 120 / 5

Mother's age = 24

Now that we know the mother's current age is 24, we can find her age 6 years ago by subtracting 6 from her current age:

Mother's age 6 years ago = 24 - 6

Mother's age 6 years ago = 18 years old.
