If the number of books in B is x, the number of books in C is (160-X) and the number of books in A is (128-X). According to the meaning of the question, it is concluded that:

128 X = 3/7( 160-X)

896-7X=480-3X

4X=4 16

X= 104

The last digit of the number is 0. If you remove 0, it is the same as the second number, which means that the big number is 10 multiplied by the decimal number.

Let the smaller of these two numbers be x, then the larger one is 10X.

X+ 10X=462

1 1X=462

X=42

The larger of the two numbers is 42* 10=420.
