Here are two methods to make a 4-digit code. Codes can have repeated digits.

Method A
For the first two digits use an even number between 29 and 100
For the last two digits use a multiple of 11

Method B
Use 4 digits in the order odd even odd even
Do not use the digit zero

How many more codes can be made with method B than with method A?
In your working you must say how many codes can be made with each method.

The radical equation 2+√2x-3 = √x+7 has a solution set [x= a0} and an extraneous root x = a1.
