Cost Price Calculation for A

This problem involves calculating the initial cost price given a series of profit and loss transactions.

Step 1: Calculate B's Cost Price

B sold the item to C at a 12% loss. C paid ₹231. This means ₹231 represents 100% - 12% = 88% of the price B paid.

Let the cost price for B be $CP_B$. We can write the equation:

$0.88 \times CP_B = ₹231$

Solving for $CP_B$:

$CP_B = \frac{231}{0.88}$

$CP_B = \frac{23100}{88} = ₹262.50$

Step 2: Calculate A's Cost Price

A sold the item to B at a 25% gain. This means B paid ₹262.50, which is 100% + 25% = 125% of A's original cost price.

Let the cost price for A be $CP_A$. We can write the equation:

$1.25 \times CP_A = CP_B$

$1.25 \times CP_A = ₹262.50$

Solving for $CP_A$:

$CP_A = \frac{262.50}{1.25}$

$CP_A = \frac{26250}{125} = ₹210$

Conclusion

The cost price of the item for A was ₹210.
