CP of First Product = X
CP of Second Prodict = Y

1.1x = 0.9y
X/y = 9/11

Lets say CPs are 90 & 110 for x & y

So, Profit/Loss = ((99+99)-(90+110))/(90+110)
= - 2/200
So, Loss of 1%

If 2 items are sold each at same price ( ie, Same S.P)
one item at a gain of P %
other at a loss of P% ,
Then overall loss = p ^2 / 100 %
hence, here P = 10,
Therefore, overall loss % = 100/100 = 1%
