The line chart given below shows the marked price and discount of six articles. J1 = Value of average marked price per article. J2 = Value of the sum of selling price of articles S and T. What is the ratio of J1 and J2? Correct Answer 21 ∶ 28
Given:
J1 = Value of average marked price per article.
J2 = Value of the sum of selling price of articles S and T.
Formula used:
Selling Price = M.P - Discount
Calculation:
J1 = Value of marked price of (P + Q + R + S + T + U)/6
⇒ (3500 + 7500 + 8000 + 3800 + 4200 + 4500)/6
⇒ 5250
Selling Price = M.P - Discount
S.P of S = 3800 - 800
⇒ 3000
S.P of T = 4200 - 200
⇒ 4000
J2 = S.P of S and T
⇒ 3000+4000
⇒ 7000
The ratio of J1 and J2
⇒ 5250 : 7000
⇒ 21 : 28
∴ Option D is correct.
