D Correct answer
Explanation

The ratio change is consistent: if P=4x and Q=7x, after P increases by 50% to 6x and Q decreases by 25% to 5.25x, the new ratio is 6x:5.25x = 8:7. However, the variable x remains unknown, so P's actual earnings in rupees cannot be determined from the given information alone.
