=====================
$\bf \: \: let \: \: the \: \: c.p. \: \: be \: Rs \: x \\ \\ \bf \: s.p. = Rs \: \: 34.40 \\ \\ \bf \: gain = 7.5\%$
Now,
=-=-=-=
$= > \: \: \bf gain = \frac{s.p. - c.p.}{c.p.} \times 100 \\ \\ or. \: 7.5 = \frac{34.4 - x}{x} \times 100 \\ \\ or. \: \: \frac{7.5x}{100} = 34.4 - x \\ \\ or. \: \: x + 0.075x = 34.4 \\ \\ or. \: 1.075x = 34.4 \\ \\ or. \: \: \bf x = \frac{34.4}{1.075} = 32$


So.. Cost price = ₹ 32.
