The cost price of two dozen bananas is Rs.34. After selling 18 bananas at the rate of Rs.14 per dozen, the shopkeeper reduced the rate to Rs.6 per dozen. The loss percent is:

29\(\frac{7}{17}\)

CP of 24 bananas = Rs. 34

SP of 18 bananas (Rs. 14 per dozen) = 14 + 7 = Rs. 21

SP of remaining 6 bananas (Rs. 6 per dozen) = Rs. 3

SP of 24 bananas = 21 + 3 = Rs 24

Loss% = \(\frac{10}{34}\) × 100 = 29\(\frac{7}{17}\)
