Step-by-step explanation:

$one \: dozen \: = 12kela \: (banana) \\ cost \: \: of \: \: 12 \: kela = rs10 \\ cost \: price \: of \: 1 \: kela= \frac{10}{12} rupees \\ selling \: price \: of \: 10 \: kela = rs12 \\ selling \: price \: of \: 1 \: kela = \frac{12}{10} \\ profit = selling \: price - cost \: price \\ = \frac{12}{10} - \frac{10}{12} \\ = \frac{72 - 50}{60} \\ = \frac{22}{60} \\ = \frac{11}{30} rupees \\ profit \: \% = \frac{profit}{cost \: price} \times 100 \% \\ = \frac{ \frac{11}{30} }{ \frac{10}{12} } \times 100\% \\ = \frac{11}{30} \div \frac{10}{12}\ \times 100\% \\ = \frac{11}{30} \times \frac{12}{10} \times 100\% \\ = \ \frac{13200}{300} \% \\ = 44\% \: ans$
