=====================
1). Let C.P be Rs x

S. P = Rs 21384

By problem,
=-=-=-=-=-=-=-=
$= > x + \frac{10}{100} x = 21384 \\ \\ = > 1.1x = 21384 \\ \\ = > \bf \: x = \frac{21384}{1.1} = rs \: 19440$
Now,

Extra profit = 2% of x

$= \frac{2}{100} \times 19440 = rs \: \: 388.8$

2) Let the C.P be Rs x

So, 3% of x = Rs 780

$= > \frac{3}{100} x = 780 \\ \\ = > x = \frac{780 \times 100}{3} = 260 \times 100 \\ \\ = > \bf \: x = rs \: \underline{26000}$
