Question

A numerical coding machine codes the word math as 62844. If the input is the word 'kind', what would the machine output be?

Answer 1

Inspecting the keypad of a phone dialler, we find:


Now, we know that the word 'math' is coded as '62844'. Pressing the corresponding digits, we find:

Digit	Number of Presses	Resulting Letter
6	1	m
2	1	a
8	1	t
4	2	h

Using the same logic for the word 'kind', we get:

Digit	Number of Presses	Resulting Letter
5	2	k
4	3	i
6	2	n
3	1	d

So, the coded output for the word 'kind' will be 55444663.
