Answer 2

Answer:

Loss = 250, Loss% = 4%

Step-by-step explanation:

SP1 = 3000, Loss=20%

CP1 = 100/100-loss ×SP1 = 100/100-20 ×3000 = 100/80 ×3000 = 3750

SP2 = 3000, Gain=20%

CP2 = 100/100+gain ×SP2 = 100/100+20 ×3000 = 100/120 ×3000 = 2500

Total CP = 3750+2500 = 6250

Total SP = 3000+3000 = 6000

CP>SP

∴ Loss of 6250-6000 = 250

Loss% = 250/6250 ×100% = 4%
