$<b>$
Let the profit be x

Which is equal to the CP OF 20 Oranges = x
Hence CP OF 1 Orange= x/20
CP of 120 Oranges
$= \frac{x}{20} \times 120 \\ = 6x$
Now profit% = Profit × 100/CP
$= \frac{x}{6x} \times 100 \\ = 16.66\%$

Let the profit be x

Which is equal to the CP OF 20 Oranges = x

Hence CP OF 1 Orange= x/20

CP of 120 Oranges

\begin{gathered} = \frac{x}{20} \times 120 \\ = 6x\end{gathered}

=

20

x

×120

=6x

Now profit% = Profit × 100/CP

\begin{gathered} = \frac{x}{6x} \times 100 \\ =

16.66\%\end{gathered}

=

6x

×100

=16.66

=16.66+0.01

=16.67%
