Answers
Step-by-step explanation:
The marked price of each item when the selling price is given as
a) mobile phone +9,000 is Rs. 12500
b) DVD player 1,440 is Rs. 2000
c) monitor 5,040 is Rs. 7000
d) pen drive *720 is Rs. 1000
Step-by-step explanation:
Let the Marked Price for each of the items be Rs. “x”.
Two successive discounts are given as 10% & 20%.
Required formulas:
Selling price = Marked Price – [Discount% of Marked Price] = Marked Price * [1 – (Discount/100)]
Now, based on the above formula the marked price for each of the items are solved below:
Case (a):
Selling price of the mobile phone = Rs. 9000
∴ x * = 9000
⇒ x =
⇒ x = Rs. 12500
Thus, the marked price of the mobile phone is Rs. 12500.
Case (b):
Selling price of the DVD player = Rs. 1440
∴ x * = 1440
⇒ x =
⇒ x = Rs. 2000
Thus, the marked price of the DVD player is Rs. 2000.
Case (c):
Selling price of the monitor = Rs. 5040
∴ x * = 5040
⇒ x =
⇒ x = Rs. 7000
Thus, the marked price of the monitor is Rs. 7000.
Case (d):
Selling price of the pen drive = Rs. 720
∴ x * = 720
⇒ x =
⇒ x = Rs. 1000
Thus, the marked price of the pen drive is Rs. 1000.
