Answer:
Present age of mother is 35 years.
Step-by-step explanation:
Let mother’s present age be x and son’s present age be y.
So, y = x/5
After 7 years,
Mother’s age = x + 7
Son’s age = x/5 + 7
Acc. to question,
x/5 + 7 = (x+ 7)/3
Solve above equation and get value of x.
You will get x = 35
Present age of mother is 35 years.
