Answer 1

Answer:

COMPUTER = RS 32000

LOSS=5%

SP=(100-loss)cp/100

(100-5)Rs32000/100

Rs=95×32000/100

Rs=95×320

Rs30400

Loss=Rs32000-Rs30400

Rs 1600

MICROWAVE=6500GAIN=5%

SP=(100+GAIN)CP/100

(100+5)Rs6500/100

Rs=105×6500/100

Rs=105×65

Rs6825

Gain=Rs6825-Rs6500

Rs325

Computer,loss=5%(Rs1600)
