Question

Mr tandon purchased a computer for 32000 and a microwave oven for 6500. On computer he lost 5% and on microwav he gained 15 %
Find his total gain or loss par

Answer 1

Cp of Computer=32000
L%=5%
Sp=(100-l%)/100×cp
=95/100×32000
=30400
Cp of Oven=6500
G%=15%
Sp=(100+g%)/100×cp
=115/100×6500
=7475
Total cp=(32000+6500)=38500
Total sp=(30400+7475)=37875
[Cp<Sp]So gain=sp -cp
=38500-37875=625
G%=625/38500×100
=1.62%

Answer 2

Answer:

Step-by-step explanation:

CP of computer=32000

CP of microwave=6500

Loss on computer=5%

Gain on microwave=15%

SP of computer=32000×(100-5)/100

=320×95

=30400

SP on microwave=6500×(100+15)/100

=65×115

=7475

Total CP=32000+6500

=38500

Total SP=30400+7475

=37875

Loss=38500-37875

=625

Loss%=625/38500×100

=125/77

=1.62Loss%
