Correct Answer: B > E > C > F > A > D

Solution : Given: The marked prices shown for A, B, C, D, E, and F are 750, 600, 650, 450, 850, and 350, respectively.
The selling prices for A, B, C, D, E, and F are 650, 450, 500, 400, 650, and 300, respectively.
Discount Percentage = $\frac{\text{( Marked price – Selling price)}}{\text{ Marked price}}\times100$
The discount percentage of A = $\frac{( 750 –650)}{750}\times100$.
⇒ $\frac{100}{750}\times 100=13.33$%
The discount percentage of B = $\frac{( 600 –450)}{600}\times100$.
⇒ $\frac{150}{600}\times 100=25$%
The discount percentage of C = $\frac{( 650 –500)}{650}\times100$.
⇒ $\frac{150}{650}\times 100=23$%
The discount percentage of D = $\frac{( 450 –400)}{450}\times100$.
⇒ $\frac{50}{450}\times 100=11.11$%
The discount percentage of E = $\frac{( 850 –650)}{850}\times100$.
⇒ $\frac{200}{850}\times 100=23.52$%
The discount percentage of F = $\frac{( 350 –300)}{350}\times100$.
⇒ $\frac{50}{350}\times 100=14.28$%
The correct sequence of the discount percentages is B > E > C > F > A > D.
Hence, the correct answer is B > E > C > F > A > D.
