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