Correct Answer - Option 3 :
100
Calculation:
Since Q computes actual profit on S.P., actual profit for Q
⇒ 25% of 2000
⇒ Rs. 500
Since P computes actual profit on C.P., C.P. for P = 2000/1.25
Rs. 1600
∴ Actual profit for A = 25% of 1600
⇒ Rs. 400
∴ Required difference
⇒ 500 − 400
⇒ Rs. 100
The actual profit made by Q more than that made by P is of Rs. 100.
