Riya purchased 2\(\frac{1}{2}\) dozen eggs at the rate of ₹20 per dozen. She found that 6 eggs were rotten. She sold the remaining eggs at the rate of ₹22 per dozen. Then her profit or loss percent is:

12% loss

CP of 2\(\frac{1}{2}\) dozen eggs = \(\frac{5}{2}\) × 20 = Rs.50

Total rotten eggs = 6

Remaining eggs = 2 dozen and C.P = Rs.50

SP of 2 dozen = 2 × 22 = Rs.44

Loss = 50 - 44 = 6

Loss % = \(\frac{6}{50}\) = 12%
