Let ,
The present age of girl and her sister be x and y
By the given condition ,
x + y = 32 or x = 32 - y ------ (i)
xy = 252 ---------------- (ii)
Put the value of x = 32 - y in eq (ii)
Put the value of y = 14 in eq (ii)
Again , Put the another value of y = 18 in eq (ii)
Girl's age = 18 yrs or 14 yrs and Girl's sister age = 14 yrs or 18 yrs
