Detailed Solution

Given, a man bought a number of clips at 3 for a rupee and an equal number at 2 for a rupee.
Let us assume that he bought 1 dozen clips of each kind.
C.P of 2 dozen =

\frac{1}{3} \times 12 + \frac{1}{2} \times 12 = Rs 10

S.P of 2 dozen =

120 % of 10

\Rightarrow

S.P of 2 dozen =

Rs \frac{120}{100} \times 10

\Rightarrow

S.P of 2 dozen =

Rs . 12

Hence S.P per dozen = Rs. 6.
So, option 3 is correct.
