Answer 2

Answer:

Therefore, The answer is 1580 kcal

Step-by-step explanation:

Given -

Apple  = 1/30
Nutrition Bar = 40/45

To find -  How much more energy does a man needs?

The total no. of kcal an apple gives  = 1/30 of to 1800 kcal

                        =1/30  X 1800 = 60 kcal

Total no. of kcal a nutrition bar gives = 40/45 of 1800 kcal

                                 = 40/45 X 1800 = 40 X 40

                                 =1600 kcal energy

Apple + Nutrition bar = Total energy

= 60 + 1600

= 1660 kcal

Therefore, More energy the human will need is = 1800 - 1660

                                                            = 140 kcal
