Q: My friend Manu is a good Photographer.
He bought two digital cameras yesterday.
Today morning he got some emergency, so he had to sell both cameras.
He sold both of them for RS. 8000 each.
On one camera he made 20% and on the other he lost 20%.
How much did he gain or lose in the entire transaction?
A: Manu lost Rs 666.67
Explanation:
Consider the first camera.
Manu made 20% on it after selling it for Rs 8000.
So the original price of first camera is:
((100+20)x)/100 = 8000
x = (8000 X 100)/120 = 6666.67
Similarly, consider second camera.
He lost 20% on it after selling it for Rs 8000.
So the original price of second camera is :
((100-20)x)/100= 8000
x = (8000 X 100) /80 = 10000
Total buying price of two cameras = Rs 6666.67 + Rs 10000 = Rs 16666.67
Total selling price of two cameras = Rs 8000 + Rs 8000 = Rs 16000
So, Manu lost (16666.67-16000)= 666.67 in the entire transaction.
