The bar chart given below shows the discount percentage offered by a shopkeeper on seven articles. Selling price of these seven articles: A1, A2, A3, A4, A5, A6 and A7 is Rs. 420, Rs. 600, Rs. 816, Rs. 825, Rs. 425, Rs. 800 and Rs. 840. Selling price = Marked price \(\left[1−\frac{\text { Discount percent }}{100}\right]\) What is the sum of the marked price of these seven articles ?
Rs. 7000
GIVEN:
Selling price and discount percentage of seven different articles from A 1 to A 7
FORMULA USED:
M.P. = 100 S.P. / ( 100 - d)
Where, S.P. = Selling price , M.P. = Marked price and d = discount%
CALCULATION:
Here, we have
S.P. of A1 = Rs420 and discount% = 30
⇒ M.P. = 100 S.P. / ( 100 -d)
⇒ M.P. = 100 × 420 / ( 100 - 30)
⇒ M.P. = 100 × 420/70 = Rs600
Now, S.P. of A2 = Rs600 and d% = 25
⇒ M.P. = 100 × 600 / 75 = Rs800
Now, S.P. of A3 = Rs816 and d = 32%
⇒ M.P. = 100 × 816 / 68 = Rs1200
Now, S.P. of A4 = Rs825 , d = 45%
⇒ M.P. = 100 × 825/55 = Rs1500
Now, S.P. of A5 = Rs425 ,d = 15%
⇒ M.P. = 100 × 425 /85 = Rs500
Now, S.P. of A6 = Rs800 , d = 20%
⇒ M.P. = 100 × 800/80 = Rs1,000
Now, S.P. of A7 = Rs840 ,d = 40%
⇒ M.P. = 100 × 840/60 = Rs1400
Total Marked Price from A1 to A7 = ( 600 + 800 + 1200 + 1500 + 500 + 1000 + 1400 ) = Rs7,000
Hence, sum of the marked price of the seven articles is Rs7,000
