Invoice Value Calculation:

Given:
Cost price of goods sent by X to Y = X
Cost plus 25% = (125/100)X
Selling price of half the goods received by Y = Rs. 1,76000
10% above invoice price = 1.10 times the invoice price

To find:
The invoice value of the goods sent by X to Y

Solution:

Step 1: Calculate the cost price of the goods received by Y
The selling price of half the goods received by Y is Rs. 1,76000. Let's assume the cost price of half the goods received by Y is CP.
So, the cost price of the goods received by Y is 2 * CP.

Step 2: Calculate the cost price of the goods sent by X to Y
The cost price of the goods sent by X to Y is (125/100)X.

Step 3: Equate the cost price of the goods received by Y and the cost price of the goods sent by X to Y
2 * CP = (125/100)X

Step 4: Calculate the invoice price
Invoice price = CP

Step 5: Calculate the selling price of half the goods received by Y
Selling price = 1.10 * Invoice price
1,76000 = 1.10 * CP

Step 6: Solve the equations to find CP and Invoice price
From Step 3, we have:
2 * CP = (125/100)X

From Step 5, we have:
1,76000 = 1.10 * CP

Solving the above two equations, we can find the values of CP and X.

Step 7: Calculate the invoice value
The invoice value is the cost price of the goods sent by X to Y, which is equal to CP.

Therefore, the invoice value will be the calculated value of CP.
