Answer 2

Answer:

loss% =  21.2%

Step-by-step explanation:

SP of video= 100-5/100*CP

SP of video=95*200

SP of video=19000

SP of TV= 100+8/100*CP

SP of TV=108*300

SP of TV=21600

total SP = 19000 + 21600

total SP = 40600

total CP = 20000 + 30000

total CP = 50000

when CP>SP

loss = CP-SP

loss = 50000- 40600

loss = 10600

loss% = 10600/50000*100

loss% = 21.2%
