Answer 1

Hey mate here we go

$two \: tv \: cost \: is \: 10000 \times 2 = 20000 \\ for \: one \: tv \: sold \: it \: for \: 10\% \: profit \\ i.e \: 10000 \times ( \frac{10}{100} ) = 10000 \times 0.1 \\ = 1000 \\ therefore \: he \: sold \: it \: 10000 + 1000 = \: 11000rps \\ \: after \: he \: sold \: one \: more \: tv \: at \: 10\% \: lose \\ i.e \: 10000 \times ( \frac{10}{100} ) = 1000 \\ so \: now \: lose \: means \: have \: to \: make \: minuse \\ i.e \: 10000 - 1000 = 9000rps \\ by \: this \: we \: can \: say \: it \: that \: he \: doesn't \: get \: lose \: or \: profite \\ bcz \: 11000 + 9000 = 20000rps \: only \: as \: original \: price \\ \: i \: hope \: this \: will \: help \: u \: \\ mark \: me \: as \: brainliest$
