easy concept

Answer 2

$Gain = \: sp - cp$

$loss = cp - sp$

$gain\% = \frac{gain \times 100}{cp}$

$loss\% = \frac{loss \times 100}{cp}$

$sp \: = \frac{100 + gain\%}{100} \times cp$

$sp = \frac{100 - loss\%}{100} \times cp$

$cp = \frac{100}{100 + gain\%} \times sp$

$cp = \frac{100}{100 - loss\%} \times sp$
