Question

Generalised form of a three-digit number abc is:

• A. 100a + 10b + c
• B. 100a + 10c + b
• C. a + 10b + 100c
• D. a + b + c

Answer 1

The correct option is A

100a + 10b + c

Assume abc is a 3-digit number, where:
a is the hundreds digit
b is the tens digit
c is the ones digit
Therefore, Generalised form of a three-digit number abc is
$100\times a+10\times b+c$
