Question 1

In the given question, out of four options, only one is correct. Write the correct answer.

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) $a\times b\times c\times d$

Answer 1

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
