after purchasing two copies of the same book,x sold the respectively at 0.8 and 1.4 times their cost prices.what was the percentage gain earned or loss incurred by x?
Answers
Answer:
10% gain
Step-by-step explanation:
Let the C.P of each copy be Rs 100
According to the question
One copy is sold at 0.8 x 100 = 80
Other copy is sold at 1.4 x 100 = 140
Total money spent in buying the copies = Rs 200
Total money earned after selling the copies = Rs (80 + 140) = Rs 220
Total gain of Rs 20. Therefore gain% = (20/220) x 100= 10%.
Given data:
After purchasing two copies of the same book for x, sold them respectively at 0.8 and 1.4 times their cost prices.
To find:
The percentage of gain or loss incurred by x
Step-by-step explanation:
Cost price of each copy = x
First copy sold at 0.8 times its cost price.
Then selling price = 0.8x
Second copy sold at 1.4 times its cost price.
Then selling price = 1.4x
Total cost price = x + x = 2x
Total selling price = 0.8x + 1.4x = 2.2x
Since total selling price > total cost price, then it was a gain for that person.
So profit = 2.2x - 2x = 0.2x
Thus profit percentage
= profit / total selling price × 100%
= 0.2x / 2x × 100%
= 10%
Answer:
Gain percentage = 10%
