Mr.Vijay is on tour and has Rs 360 for his expenses.if he exceeds his tour by 4 days he must cut down daily expense by Rs 3.The number of days of Mr.Vijay's tour program is?

• 20 days
  
  Let the number of days of your be x, then daily expense =360/x
  When days increases by 4, daily expense decreases by 3 Rs. So 360/(x+4) =(360/x) - 3
  => x^2 + 4x - 480 = 0
  => (x-20) (x+24) = 0
  So, x=20
