Question

total weight of a bag with 8 books inside is 2kg 340g.if the bag alone weight 950g, what is the weight of food?​

Answer 1

Answer:

B = 3kg 450 g ; C = 2kg 550 g

Step-by-step explanation:

total weight = 8kg 950 g = 8950 g

weight of bag A= 2 kg 900 g = 2900 g

weight of bag C = x g

weight of bad B = x + 900g

weight of bag A and B = ??

total weight = weight of bag A + weight of bag B + weight of bag C

     8950 g =     2900 g           +         (x + 900 g)   +   x g

     8950 g =      3800 g           +       2x

8950-3800= 2x

    5100 g  = 2x

    5100/ 2 g = x

                 x = 2550 g

      weight of bag C = x g = 2550 g = 2kg 550 g

      weight of bag  B = x+ 900 g = 2550 + 900g = 3450 g = 3kg 450 g

Answer 2

Step-by-step explanation:

weight of bag with books=2kg 340g

2x1000g+340g=2340g

weight of bag=950g

weight of books = 2340g-950g

=1390g
