Answer»

Suppose Sara's age = X

So, Sara's Sister Ann age = X-3

Mother age = Sara's age * 3 X*3 = 3X

or = Ann's age * 4 = 4 (X - 3)

Step by step EXPLANATION:

find the value of X

3X = 4 (X-3)

3X = 4X-12

12 = 4X-3X

X = 12

So Sara's age = X

Mother's age = 3X = 3 * 12 = 36

Anna's is age = X-3 = 12-3 = 9

Step by step EXPLANATION:

find the value of X

3X = 4 (X-3)

3X = 4X-12

12 = 4X-3X

X = 12

So Sara's age = X

Mother's age = 3X = 3 * 12 = 36

Anna's is age = X-3 = 12-3 = 9
