A man bought a number of clips at 3 for a rupee and an equal number at 2 for a rupee. At what price per dozen should he sell them to make a profit of 20\%?
(a)₹ 4
(b)₹ 5
(c)₹ 6
(d)₹ 7
Answer
Answer (as printed): C
Explanation
Suppose he bought 1 dozen clips of each kind. $$\begin{aligned} & \text { C.P. of } 2 \text { dozens }=₹\left(\frac{1}{3} \times 12+\frac{1}{2} \times 12\right)=₹ 10 . \\ & \therefore \text { S.P. of } 2 \text { dozens }=120 \% \text { of } ₹ 10=₹\left(\frac{120}{100} \times 10\right)=₹ 12 . \end{aligned}$$ Hence, S.P. per dozen = ₹ 6.
