Best answer
Cost Price of Computers are 20000(the one on which he has profit) and 30000 (loss)
Total cost price=50000
Total selling price = 48000
$\therefore$ Loss percent = 4 %

Simple formula, if an item is sold at same price in both cases, and if there is x% loss in one case, while x% profit in the other, than overall, there is LOSS.
And, Loss% = (x/10)^2.
Therefore, here there is LOSS, and
Loss% = (20/10)^2 = 4%

sp1 = 24000
for the first comp. he gained 20% profit which is equal to 1/5
cp1 : sp1
denominator: denominator+nominator
5 : 6
5*4000=20000:6*4000=24000
sp2 = 24000
for the first comp. he loss 20% which is equal to 1/5
cp2 : sp2
denominator: denominator-nominator
5 : 4
5*6000=30000:4*6000=24000
total cost price cp = cp1+cp2 = 20000+30000 = 50000
total selling price sp = sp1+sp2 = 24000+24000 = 48000
total loss = 50000-48000 = 2000
hence cp : sp
50000:48000
25:24
1/25*100 = 4%
he got loss of 4% answer.
