An amount is distributed among X, Y and Z in the ratio of 3 : 5 : 7 and another amount is equally distributed between P and Q. If the difference between the amount of Y and Q is Rs. 3500, how much amount will P get?

The question provides two separate distribution scenarios but only gives the difference between Y and Q amounts. We cannot determine either total amount since we have only one equation with multiple unknowns. The ratio gives Y = 5x, and equal distribution gives Q = y/2, but knowing Y - Q = 3500 doesn't let us solve for x or y individually. Therefore, data is inadequate to find P's share.
