Story ended with hue and cry without the aftermath. Man by nature is egoist without feeling guilty of his act whether right and wrong.But we needed to make comment only after having solved equations with the right formulas and anwer. Problem is whether permit to land? Variable is without Visa. Formula is without Visa entry is not allowed? Now any of aware human mind including both childrens affected with the drama can solve the puzzle. So,our conclusion include there is enough evidence that parents are responsible for the episode occured.
Now question is same problem will replicate its answer in each situation. I think absolutely no,type of variable may affect the solution and even formula to solve the problem will change with the some added conditions to variable.Now before solving any problem we usually peruse available literature including the same problems and their conclusions. This ease us to solve the repeated problem if occuring again.
