Explanation:

i) Selling price of a bicycle (s.p) = Rs 819

Lose (l) = 9%

Let the cost price ( c.p) =Rs c

\boxed {c.p= \frac{s.p\times 100}{100-l}}c.p=100−ls.p×100

\implies c.p = \frac{819\times 100}{100-9}⟹c.p=100−9819×100

\implies c.p = \frac{819\times 100}{91}⟹c.p=91819×100

\implies c.p = 9\times 100⟹c.p=9×100

\implies c.p = Rs900⟹c.p=Rs900

ii) If REENA wants sell it to make a profit 5%

\implies s = 9\times 105⟹s=9×105

\implies s = Rs\:945⟹s=Rs945

Therefore,

REENA has to sell the bicycle at Rs 945 tomake a profit of 5%
