Answer 2

Answer:

loss1%

Step-by-step explanation:

sp=1980

profit=10%

cp= 100/(100+P)*sp

=(100÷110)*1980

=1800

sp=1980

loss=10%

cp=100/(100-L)*sp

=(100÷90)*1980

=2200

cp 0f two cell phone=1800+2200

=4000

sp 0f two cell phone=1980+1980

=3960

cp>sp

there fore loss

loss=4000-3960=40

loss%=(40÷4000)*100=1%
