True Khaobadi. However, it is not possible to solve it by mathematical equations as asked by Ganapati It is easier to do this mathematics because value of X is either of 1, 2, 3, 4. What if X is 1000.
We cannot solve this by any equations. Because there are 3 Unkowns and only 2 equations. Only thing we can resort is trial and error. Fortunately in this question there is ONE and Only one answer.
Normally, in these types of questions there are possiblitiy of set of answers and not single answer.
