The correct Answer is:
To solve the problem step-by-step, we will define variables, set up equations based on the information given, and solve for the price of the chair. ### Step 1: Define the Variables Let the price of a chair be ₹X. Let the price of a table be ₹Y. ### Step 2: Set Up the Equations From the problem, we know two things: 1. The total cost of 3 tables and 2 chairs is ₹1850. This can be expressed as: \[ 3Y + 2X = 1850 \quad \text{(Equation 1)} \] 2. A table costs ₹75 more than a chair. This can be expressed as: \[ Y = X + 75 \quad \text{(Equation 2)} \] ### Step 3: Substitute Equation 2 into Equation 1 Now we will substitute the value of Y from Equation 2 into Equation 1: \[ 3(X + 75) + 2X = 1850 \] ### Step 4: Simplify the Equation Distributing the 3 in the equation: \[ 3X + 225 + 2X = 1850 \] Combining like terms: \[ 5X + 225 = 1850 \] ### Step 5: Isolate the Variable Now, we will isolate X by subtracting 225 from both sides: \[ 5X = 1850 - 225 \] Calculating the right side: \[ 5X = 1625 \] ### Step 6: Solve for X Now, divide both sides by 5 to find the value of X: \[ X = \frac{1625}{5} \] Calculating the division: \[ X = 325 \] ### Step 7: Conclusion The price of the chair is ₹325. ---
