Question

Mr. Mehta purchased a video for Rs20000 and a television for

for Rs3000. On the video he lost 5% and on the television he

gained 8%. Find his total gain or loss %.​

Answer 1

Video=>

CP=20000

loss=5*20000/100

= 1000

SP=20000-1000

=19000

TV=>

CP=30000

loss=8*30000/100

= 2400

SP=30000+2400

=32400

therefore,

total CP=20000+30000

=50000

total SP=19000+32400

= 51400

therefore, profit=51400-50000

=1400

therefore, profit%=(1400/50000)*100

=2.8% gain.....
