medium
A vendor buys bananas at $9$ for $Rs. 8$ and sells at 8 for $Rs. 9.$ What will be the profit or loss (in $\%$)?
A
$13.28 \%$ profit
B
$26.56 \%$ loss
C
$26.56 \%$ profit
D
$13.28 \%$ loss
Solution
$C.P$ of $9$ bananas $=₹ 8$ $S.P$ of $8$ bananas $=₹ 9$
$\therefore$ $C.P$ of $72$ bananas $=₹ 64$
$S.P$ of $72$ bananas $=₹ 81$
$P\%$ $=\frac{81-64}{64} \times 100$
$=\frac{17}{64} \times 100=26.56 \%$
