The cost of a dozen bananas is Rs 180.  

∴ The cost of 12 bananas is Rs 180.  

∴ The cost of 1 banana is = Rs (180/12)  

                                        = Rs 15  

∴ The cost of 1 banana is Rs 15.  

The cost of 8 lemons is Rs 56.  

∴ The cost of 1 lemon is = Rs (56/8)  

                                       = Rs 7  

∴ The cost of 1 lemon is Rs 7.  

∴ The ratio of the cost of banana to the cost of lemon is_   15:7  

= 15/7      

= 15:7 [∵ There is no common multiple between 15 and 7 except 1.]  

Hence, the ratio is 15:7
