Answer fast​

Answer 1

Answer:

Hey mate...

here is your answer:-

Step-by-step explanation:

Let the sum of ages of the sisters = x.

Let mother’s age = y.

So x/4=7

x=7×4

x=28.

Now (x+y)/(4+1) = 7+6

(28 + y)/5 = 13

28 + y = 13 × 5

28 + y = 65

Therefore y = 37.

Thus the age of the mother is 37 years.
