Question

What ans is of this and how it come 8/ 56X 152 ans and how it comes

Answer 1

Step-by-step explanation:

Unitary method

56 books= 8kg

1 book will weigh= 8/56 kgs

So 152 such books will weigh= 8/56 x 152

                                               =21.714 kgs

Now, we have been asked how many such books will weigh upto 5 kg....

If 8 kg weight is of 56 books

Then 1 kg will be the weight of 56/8 books

And 5 kg will be the weight of 56/8 x 5 books

i.e., 7x5= 35 books

Hence 35 books will weigh upto 5 kg
