\boxed{ \sf \: 7500 \times ( \frac{100}{100 + 20} )}

7500×(

100+20

100

)

\sf \: 75000 \times \frac{100}{120}75000×

120

100

= 6250=6250

\sf \: Profit =7500-6250=1250Profit=7500−6250=1250

Cost of second speaker

8100 \times ( \frac{100}{100 - 10} )8100×(

100−10

100

)

\sf \: 8100 \times \frac{100}{90}8100×

90

100

= 9000=9000

\sf \: Loss= 9000-8100=900Loss=9000−8100=900

\sf \: So \: Profit=1250-900=350SoProfit=1250−900=350
