48 per dozen of pencils ⇒ Price of one pencil=4 Sold 3 for 15 ⇒ One for 5 11 2 dozen = 11 2 ⋅ 12 = 66 C.P. of 66 = 264 and S.P. of 66 = 330 Total profit = 330 − 264 = 66 \text{48 per dozen of pencils }\Rightarrow\text{Price of one pencil=4} \\ \text{Sold 3 for 15}\Rightarrow\text{One for 5} \\ \frac{11}{2}\text{dozen}=\frac{11}{2}\cdot12=66 \\ \text{C.P. of } 66=264 \text{ and } \text{S.P. of } 66=330 \\ \text{Total profit} = 330-264=\boxed{66}
