The general form of a 2 -digit number is (tens digit × 10 ) + ones digit .

A number is said to be in a generalised form if it is expressed as the sum of the product of its digits with their respective place values. Thus, a two-digit number having a and b as its digits at the tens and the ones places respectively is written in the generalised form as 10 a + b , where ‘ a ’ can be any of the digits from 1 to 9 And ‘ b ’ can be any of the digits from 0 to 9 . Hence, the solution.

The general form of a 3 -digit number is (hundreds digit × 100 ) + (tens digit × 10 ) + ones digit .

A number is said to be in a generalised form if it is expressed as the sum of the product of its digits with their respective place values. Thus, a three-digit number having a and b as its digits at the tens and the ones places respectively is written in the generalised form as 100 a + 10 b + c , where ‘ a ’ can be any of the digits from 1 to 9 while ‘ b ’ and ' c 'can be any of the digits from 0 to 9 . Ex: 507 = 5 × 100 + 0 × 10 + 7 × 1 Hence, the solution.
