Answers
Answer:
500
Step-by-step explanation:
Given
Selling price = Rs 540
To find : Cost Price
Let the cost price be x
Now , We know that discount is Like loss
So, We will write 10% discount as 90 .
Marked price = (Selling price × 100 ) / 90
= (540×100)/90
= 54000/90
= Rs 600
Profit = (100× profit ) / CP
20 = 100× (600-x) / x
20 = (60000 - 100x ) / x
20x = 60000-100x
20x+100x = 60000
120x = 60000
x = 60000/120
x = Rs 500
Therefore , the Cost price of the watch is Rs 500 .
