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
