Radha purchased a Computer table for ₹10000 and a Centre table for ₹5000. She sold Computer table with 8% profit. With what profit percent should she sell the Centre table so as to gain 10% on the whole transaction?
Answer & explanation
Correct answer: option 3
Cost price of a computer table = Rs.10000
Cost price of a centre table = Rs.5000
Profit % for computer table = 8%
SP - CP = Profit
Selling price of a computer table = 10000 × \(\frac{108}{100}\) = Rs.10800
Total cost price of computer table and centre table = 10000 + 5000 = Rs.15000
Selling price of a computer table and centre table = 15000 × \(\frac{110}{100}\) = Rs.16500
Selling price of a centre table = 16500 - 10800 = Rs.5700
Profit % when selling price of a centre table = \(\frac{(5700 - 5000)}{ 5000}\) × 100 = 14%
