Ram buys 4 chairs and 9 stools for ₹ 1,340. If he sells chairs at 10% profit and stools at 20% profit, he earns a total profit of ₹ 188. How much money did he have to pay for the chairs ?
Elementary MathematicsProfit and Loss
- A₹ 200
- B₹ 400
- C₹ 800
- D₹ 1,600
Explanation
Let chairs cost C and stools S, with C+S = 1340. Total profit: 0.1C+0.2S = 188. Substituting S = 1340−C: 0.1C+268−0.2C = 188, so 0.1C = 80 and C = 800. Hence option (C) ₹800.
