Question

A VCR and TV were brought from R.s 15,500. R.s 8,000 each. The shopkeeper made a loss of 4% on the VCR and a profit of 8% on the TV. Find the gain or loss percent on the whole transaction.​

Answer 1

Answer:

he has a profit of 4% as he has profit of 8% on TV - 4% loss on VCR

Answer 2

$\huge \boxed{SOLUTION}$

C.P of TV = 8000

Profit % on TV = 8%

$\sf{ 8p \: of \: tv = 8000 + 8000 \times \frac{8}{100} }$

$\sf = 8000 + 640$

$\sf s.p \: of \: tv = 8640$

$\sf c.p \: of \: vcr = 8000$

$\sf loss \: percentage \: on \: vcr = 4$

$\sf s.p \: of \: vcr = 800 - \frac{800 \times 4}{100}$

$\sf = 8000 - 320$

$\sf s.p \: of \: vcr = 7680$

Total C.P of TV and VCR = 8000 + 8000

= 16000

Total s.p of TV and VCR = 8640
