Question

Generalised form of a four- digit number abdc is

• A. 1000a + 100b + 10c + d
• B. 1000a + 100c + 10b + d
• C. 1000a + 100b + 10d + c
• D. $a\times b\times d\times c$

Answer 1

The correct option is C 1000a + 100b + 10d + c

In generalised form, we express a number as the sum of the products of its digits with their respective place values.
$\therefore$ abdc is written in generalised form as 1000a + 100b + 10d + c
i.e. abdc = 1000a + 100b + 10d + c

Therefore, option c is correct.
