WITH EXPLANATION​

Answer 1

Answer:

Hey mate hope it will help you!

an apple gives = 1/30 of total energy that is 1800 kcal

                         =1/30 * 1800 = 60 kcal energy

a nutrition bar gives = 40/50 of total energy that is 1800 kcal

                                  = 40/50 * 1800 = 40 * 36

                                  =1440 kcal energy

now total energy we get from apple and nutrition bar = 60 + 1440

                                                                                          = 1500 kcal

more energy the human will need is = 1800 - 1500

                                                             = 300 kcal
