Answer: 33 years
Step-by-step explanation:
Let present age of Rohan and his mother be x and y respectively.
By question,
x=y+26....(1)
& (x+3)(y+3)=360.....(2)
Or, xy+3x+3y+9=360
Or, x(x-26)+3x+3(x-26)+9=360
Or, x^2-26x+3x+3x-78+9=360
Or, x^2-20x-429=0
Or, x^2-33x+13x-429=0
Or,x(x-33)+13(x-33)=0
Therefore x=33 &x= -13
Of the two values obtained, x= -13 is not possible because age cannot be negative.
Hence x=33 years.
