Answer:
SP of 2 laptops =Rs.48000
SP of 1 laptop=Rs 48000 divide by 2
=Rs.24000
gain=20perent
CP=sp*100\100+gainpercent
24000*100\100+20
2400000\120
20000
loss=20percent
CP=24000*100\100 -20
2400000\80
30000
Step-by-step explanation:
Total CP= 20000+30000= 50000
LOSS= CP-SP
=50000-48000
=2000
losspercent=loss\CP*100
2000\50000*100
4percent
therefore, his loss percent is 4percent.
