Let the CP be Rs 100.
Loss = 10%
SP will be Rs 90.
Now, By Unitary method ,
If 90 is SP ,then 100 is CP.
So, If 99 is SP , CP will be 100/90 *99 = 110 .
Again, Gain = 10%
SP will be 110 .
Now, By Unitary method,
If 110 is SP , 100 is CP.
So, if 99 is SP , CP will be 100/110 *99= 90.
So, Total SP = (99+99)= 198.
Total CP = (110+90)= 200.
Thus, Loss = (200-198)= 2.
Loss % = 2/200*100 = 1%.
