11-Plus Exam Illustrations - Verbal Reasoning Quiz - VR - Codes (2) (Questions)


These three words are given in code. The order is mixed up.

DEAL 5431
CLAD 4621
LIED 1234

Find the code for the word DELL.

This is a logic-based question rather than one which needs knowledge of words. It's similar to a Sudoku puzzle in the sense that you get presented with numbers and yet it needs no mathematics whatsoever.

If you are presented with a multiple-choice answer list then you will be able to find the answer in a different way to if you aren't. Let's start with the 'no choices' situation.

In order to sort out which code goes with which word, see what they have in common. The first two code numbers end in '1' so these must relate to 'CLAD' and 'LIED' as both of these words end in the same letter. This means '1' represents 'D'.

If '1' is 'D', it means '1234' must be the code for 'DEAL'. Now we know 'E' is represented by '2', 'A' by '3' and 'L' by '4'. This is all we need to work out the code for 'DELL' - it must be '1244'.

Now let's look at a slightly quicker method should there be a set of multiple-choice answers provided.

Choose the correct answer:

5422 - 1234 - 1244 - 4621 - 4612

We immediately know it must end in two of the same number as 'DELL' ends in a double letter. The only possibilities are therefore '1244' and '5422'.

We might then use the previous method to be certain or use a different approach - perhaps we could see that 'L' must be either '2' or '4'. Look at the original codes. Given that 'DEAL' ends in 'L' we would need there to be a '2' at the end of a code but there isn't, so it's not possible that 'L' is '2'. The only possible answer is '1244'

Example 2

Here are five words:

A) dole B) mole C) doll D) mode E) dome

Below, you will find the same five words written in a secret code, and in a different order. All the words are written in the same code. Work out what each coded word stands for.

α β π µ

α β λ µ

π β α µ

π β λ µ

α β λ λ

The first thing I'd teach a child is to search for similarities and differences between the codes, and look for links between those and the words provided. The clearest similarity is that all but one of the codes ends in 'µ' so this must represent the letter 'e' as four of the words end in 'e'. 'Doll' is the only word to end in anything else so 'λ' is the code for 'l'.

All the words have 'o' as the second letter - the codes show that the equivalent must be 'β'. Three of the words start with 'd' so, as three of the codes start with 'α', they must mean the same thing. That leaves 'm', which starts two of the words, being the equivalent of 'π' as it starts two of the codes.

The answers must therefore be:

α β π µ dome
α β λ µ dole
π β α µ mode
π β λ µ mole
α β λ λ doll
