CP of 2 computer = 16000×2 = 36000
SP of 1 computer at gain of 5% = 5% of 36000
=> 5/100×36000
=> 1800
New price = 16000+1800
= 17800
SP of computer at loss of 4% = 4% of 16000
=> 4/100×16000
=> 640
New price = 16000-640
=> 15360
Total SP. => 17800+15360
=> 33160
Total CP => 36000
Gain in whole transaction = 36000-33160
=> 2840
gain % = 2840/36000×100
= 7.85
hence, there is a gain of 7.85 %
