Answer & Solution
Correct Answer: Option C
40% discount on 500 = $$\frac{{40 \times 500}}{{100}}$$   = Rs. 200

500 ===30% discount ⇒ Rs. 350
350 ===10% discount = 315
Total discount in first case = Rs. 200
Total discount in second case = 500 - 315 = Rs. 185
So, difference = Rs. 15

Applying successive discount :
30+10+(30*10)/100 = 43%
Diff. discount = (43 - 40)% = 3%
At discount 40% ⇔ 500*(40/100) = 200
ATQ,
40% ≡ 200
3% ≡ (200*3)/40 = 15 (Ans.)
