1. 14%
2. 18%
3. 12%
4. 10%

Answer 1

Correct Answer - Option 1 : 14%

Given:

Cost price of a computer table = Rs.10000

Cost price of a centre table = Rs.5000

Profit % for computer table = 8%

Formula:

SP - CP = Profit

Profit % = (SP - CP)/CP × 100

Calculation:

Selling price of a computer table = 10000 × 108/100 = Rs.10800

Total cost price of computer table and centre table = 100000 + 5000 = Rs.15000

Selling price of a computer table and centre table = 15000 × 110/100 = Rs.16500

Selling price of a centre table = 16500 - 10800 = Rs.5700

Profit % when selling price of a centre table = (5700 - 5000)/5000 × 100 = 14%

∴ Profit % for centre table is 14%.
