Question

I sold two watches for rs. 300 each, one at a loss of 10% and the other at a profit of 10%. what is the percent loss (- ) or the percent profit (+) that resulted from the transaction?

Answer 1

Hi friend,

# (-) 4 ( Loss)

Solution :-

In my views , this cases always occur loss. So, the Formula of this sum :-

➡️ ( loss / gain percentage )^2 / 100 = 4

Thus, that is 4% of loss.

OR,

100= 20% (Loss) ==> 120= 20% ( gain)
==> 96

so, The % of loss = 4...i hope it helps you

Answer 2

Answer:1% loss

Explanation:

Let's assume SP as 990( LCM of 110 and 90)

Now,

1st case

CP= 100x

SP= 90X

Now,

90x= 990

Therefore,

X= 11

CP= 100*11= 1100

..

2nd case

CP= 100x

SP= 110x

Now,

110x = 990

Therefore,

X= 9

CP= 100*9= 900

TOTAL CP= 2000

total SP= 990+990= 1980

Loss%= 2000-1980= 20/ 2000*100

= 1% loss
