Answer 1

Answer:

Step-by-step explanation:

let the cost of 1kg of banana=2x

cost of 1kg of mangoes=19x

now;

cost of ikg of banana=(20% of 2x)+2x

                                  =2x/5+2x

                                     12x/5

cost of 1kg of mangoes=(40% of 19x)+19x

                                       = 266x/10

new ratio=12x/5:266x/10

               =12:133
