Question

the age of sony and her mother together is 72.If the mother's age is 3times that of sony, find their present ages.
​

Answer 1

Answer:

Mother's age is 54 years

Sony's age is 18 years

Step-by-step explanation:

Let us take the age of Sony's mother as x and Sony's age as y.

So, according to the question,

x + y = 72 and

x = 3y

Then,

3y + y = 72

4y = 72

y = 72/4

y = 18

Now,

x = 3y

x = 3 × 18

x = 54
