2. The usual form of 100xa+10xC+b is :
a)abc.
b)acb
c)bca​

Answer 1

The usual form of 100 × a + 10 × c + b is :

b) acb

Explanation:

A number 100x + 10y + z could be written as xyz. Here x, y and z corresponds with a, c and b respectively. So the usual form is acb.

We use decimal number system for doing daily calculations (There are other number system,too like binary number system, octal numerals etc ) , which has its base as 10, So in xyz, y is 10 times z. and x in 10 times y i.e. 100 times z.

likewise acb, we had c and a 10 times and 100 times greater than b.

So, the correct option is b
