Answer 1

Answer:

Cost price of video =Rs 20000

Cost price of television =Rs 30000

Lost % on video =5%

Gain % on television =8% 

Lost %=CPCP−SP×100

5=2000020000−SP×100

1000=20000−SP

SP=19000

Gain %=CPSP−CP×100

8=30000SP−30000×100

2400=SP−30000

SP=32400

Total cost price =Rs 20000+Rs 30000

=Rs 50000

Total selling price =Rs 19000+Rs 32400

=Rs 51400

Total selling price − Total cost price 

=Rs 51400−Rs 50000=Rs 1400

He had a Gain of Rs 1400

Gain %=CPGain×100

Answer 2

Step-by-step explanation:

Cost price of video =Rs 20000

Cost price of television =Rs 30000

Lost % on video =5%

Gain % on television =8%

Lost %= CP-SP/C.P× 100

5= 20000−SP/20000× 100

1000=20000−SP

SP=19000

Gain %= SP−CP/C.p ×100

8= S. p- 30000 / 30000 ×100

2400=SP−30000

SP=32400

Total cost price =Rs 20000+Rs 30000

=Rs 50000

Total selling price =Rs 19000+Rs 32400

=Rs 51400

Total selling price − Total cost price

=Rs 51400−Rs 50000=Rs 1400

He had a Gain of Rs 1400
