Answer:
4 years
Explanation:
Let x be the age ( in years ) of each daughters,
∵ Mother is 30 years older than her daughters,
⇒ Age of the mother = x + 30
Now, after 2 years,
The age of each daughter = x + 2,
And, the age of the mother = x + 30 + 2 = ( x + 32 ) years,
According to the question,
3(x+2+x+2) = x + 32
3(2x+4) = x + 32
6x + 12 = x + 32
5x = 20
⇒ x = 4
Hence, each of the daughters is 4 years old.
