The Correct Option is A
Solution and Explanation
Step 1: Relate SP and CP.
A 10% profit means \[\text{SP} = 110\% \text{ of CP} = 1.10 \times \text{CP}\] Step 2: Solve for CP.
\[\text{CP} = \dfrac{660}{1.10} = \boxed{600}\]
A 10% profit means \[\text{SP} = 110\% \text{ of CP} = 1.10 \times \text{CP}\] Step 2: Solve for CP.
\[\text{CP} = \dfrac{660}{1.10} = \boxed{600}\]
