The product of ages of Harshit and Haritika is 240. If Hritika would have been twice her age she will be 4 years elder to Harshit. What is Haritika's age now?
1) 16 yrs
2) 24 years
3) 12 years
4) 10 years
5) 15 years

• x*y=240
  2y=x+4
  (2y-4)=x
  2y^2-4y-240=0
  y=12 years

• let harshit be x yrs then haritika be 240/x.
  2*(240/x)=4+x;
  2*(240/x)-x=4; 480-x^2=4x; x^2 +4x-430=0; (x+24)(x-20)=0; x=20;
  here haritika age =(240/20)=12 yrs

• let harshit be x and haritika be y then,
  x*y=240 -----eq(1)
  y=2x+4 --------eq(2)
  now, x=240/y
  putting x=240/y in eq(2)
  then, y=2*(240/y)+4
  by solving these eq we get, y=24
  therefore haritika's age is 24 years

• Let harshit be x year and haritika be y year
  
  x*y=240 therefore x=240/y--------------eq1
  2y=x+4----------- eq2
  subtitute value of x in eq2
  2y=240/y+4
  we get Quadratic Equation
  y2-2y-120=0
  factors of eqations are
  y=12 and y=-10
  ans=12 beacause age is always positve value
