Maths Problem on Age
Question 1) The sum of the age of a mother and her daughter is 50 years . Also 4 years ago , the mothers age was 6 times the age of the daughter. What are the present age of the mother and daughter?

X-4 = 6 ( Y -4)
6Y - X = 20 -----------------2
adding 1 and 2
7Y = 70
So daughter present age 10 and mother age is 40.
Total + Number of year ago ( Times -1 )
Daughter Age = -------------------------------------------------------------------------------------
Times + 1
