Step-by-step explanation:

total \: cp \:  = 20000 + 30000 \\   \:  \:  \:  \:  \:   \:   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \: = 50000 \\ now \\ sp \: of \: video =  cp \times (1 -  \frac{loss\%}{100})  \\  = 20000 \times (1 -  \frac{5}{100} ) \\  = 20000 \times (1 -  \frac{1}{20} ) \\  = 20000 \times ( \frac{20 - 1}{20} ) \\  = 20000 \times  \frac{19}{20}  \\  = 1000 \times 19 \\  = 19000 \\  \\ now \\ sp \: of \: tv = cp \times( 1 +  \frac{gain\%}{100} ) \\  = 30000 \times (1 +  \frac{8}{100} ) \\  = 30000 \times (1 +  \frac{2}{25} ) \\  = 30000 \times ( \frac{25 + 2}{25} ) \\  = 30000 \times  \frac{27}{25}  \\  =1200 \times 27 \\  = 32400 \\  \\ total \: sp \:  = 19000 + 32400 \\  = 51400 \\  \\ so \: gain = 51400 - 50000 \\  = 1400 \\  \\ now \\ gain\% =  \frac{gain}{cp}  \times 100 \\  =  \frac{1400}{50000}  \times 100 \\   =  \frac{14}{5}  \\ = 2 \frac{4}{5} \% \\  \\ therefore \: gain\% = 2 \frac{4}{5} \% \\  \\ hope \: it  \:  helps  \:  you...... \\ please \: mark \: my \: answer \: as \: \\ brainleist.......
