Answer:
The age of three girls as
The age of Allison's is 8 years
The age of Kali is 48 years
The age of Lauren's is 24 years
Step-by-step explanation:
Let The age of Allison's = A years
The age of Lauren's = L years
The age of Kali's = K years
Now, According to question
The sum of total ages of the three girl's = 80 years
I.e A + L + K = 80 years
And ,
The age of Allison's = of The age of Lauren's
I.e A = × L
And ,
The age of Kali's = 2 times The age of Lauren's
I.e K = 2 × L
∴ × L + L + 2 × L = 80
Or, L + 3 L = 80
Or, L = 80
So, 10 L = 3 × 80
∴ L =
I.e L = 24
The age of Lauren's = 24 years
Again ,
K = 2 × L
Or, k = 2 × 24
∴ k = 48
The age of Kali = 48 years
Similarly
A = × L
Or, A = × 24
∴ A = 8 years
The age of Allison's = 8 years
Hence The age of three girls as
The age of Allison's is 8 years
The age of Kali is 48 years
The age of Lauren's is 24 years Answer
