(483*483*483+ 517*517*517) / (517*517 - 517*483 + 483*483) = ?
(a) 1 (b) 23.4568-(c) 5436948 (d) 1000

• (d) 1000
  
  if x=483 & y=517 then
  
  (483*483*483+ 517*517*517) / (517*517 - 517*483 + 483*483)
  = (x^3+y^3)/(x^2-xy+y^2)
  = (x+y)
  = 483+517
  = 1000

• a^3+b^3=(a+b)(a^2-ab+b^2) so ans is 1000

• its in the form of (a^3+b^3)/(a^2-a*b+b^2)
  now a^3+b^3=(a+b)*(a^2-a*b+b^2)
  thus thus two terms get cancelled which are common in the two expressions thus we get left term a+b=1000

• (483^3+ 517^3) / (517^2 - 517*483 + 483^2) = (a^3+b^3)/(a^2-ab+b^2)= (a+b)
  so, (517+483)= 1000 ans-> (d)
