A man sold a chair and table together for rupees 1520 thereby making a...
Given:
- Total selling price of chair and table = Rs. 1520
- Profit on chair = 25%
- Profit on table = 10%
- If sold together for Rs. 1535, profit on chair = 10% and profit on table = 25%
To find:
- Cost price of chair and table
Solution:
Let the cost price of the chair be C and the cost price of the table be T.
Case 1: Selling price = Rs. 1520
- Profit on chair = 25%
- Profit on table = 10%
Given that the selling price of the chair and table together is Rs. 1520 and the profit on chair is 25%, we can write:
C + T + 0.25C + 0.1T = 1520
Simplifying the above equation, we get:
1.25C + 1.1T = 1520 --- (1)
Case 2: Selling price = Rs. 1535
- Profit on chair = 10%
- Profit on table = 25%
If the chair and table are sold together for Rs. 1535 and the profit on chair is 10%, we can write:
C + T + 0.1C + 0.25T = 1535
Simplifying the above equation, we get:
1.1C + 1.25T = 1535 --- (2)
Now, we have two equations (1) and (2) with two variables C and T. We can solve these equations simultaneously to find the values of C and T.
Multiplying equation (1) by 5 and equation (2) by 4, we get:
6.25C + 5.5T = 7600 --- (3)
4.4C + 5T = 6140 --- (4)
Multiplying equation (4) by 1.25, we get:
5.5C + 6.25T = 7675 --- (5)
Subtracting equation (3) from equation (5), we get:
-1.25C + 0.75T = 75
Multiplying the above equation by 4, we get:
-5C + 3T = 300
Multiplying equation (4) by 5, we get:
22C + 25T = 30700
Adding the above two equations, we get:
17T = 30400
T = 1790.59
Substituting the value of T in equation (4), we get:
4.4C + 5(1790.59) = 6140
C = 900.55
Therefore, the cost price of the chair is Rs. 900.55 and the cost price of the table is Rs. 1790.59.
Answer:
- Cost price of chair = Rs. 900.55
- Cost price of table = Rs. 1790.59
