Question

By selling two transistors for rupees 600 each a shopkeeper gains 20% on one transistor and loses 20% on the other
Find:. (i) Cost price of each transistor
(ii) total cost price and total selling price of both the transistor
(iii)profit or loss percent on the whole​

Answer 1

Answer:

1. CP1 = 500, CP2 = 750

2. total SP = 1200, total CP = 1250

3. 4% loss

Step-by-step explanation:

1.

a). 120% of CP = 600.

    CP = (600x 100)/120 = 500

b). 80% of CP = 600.

    CP = (600x100)/80 = 750.

2.

total SP = 600+600 = 1200

total CP = 500+750 = 1250

3.

Formula: if selling price is same and there is x% loss and x% gain on each.

In this case it will always be a loss of = (x^2)/100 % = (20x20)/100 = 400/100 = 4% loss.
