Question

Generalized form of a four-digit number $abdc$ is

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

Answer 1

The correct option is C

$1000a+100b+10d+c$

Explanation for the correct option:

Given, four-digit number is $abdc$

We know that, the numbers are expressed as the sum of the product of it digits with the respective place value.

Here,

• The place value of $a$ is $1000$.
• The place value of $b$ is $100$.
• The place value of $d$ is $10$.
• The place value of $c$ is $1$.

So, the generalized form of $abdc$ is $1000a+100b+10d+c$

Hence, the correct option is option C.
