Question

1.Spooky has a favourite number. It is a 2 digit number. The total of the digits is 10. It is an even number It is less than 30. What is it? .........

​

Answer 1

10

Explanation:

Even numbers less than 30 are:

2,4,6,8,10,12,14,16,18,20,22,24,26,28

We know it has two digits so we can cross out:

2,4,6,8

We are left with the last piece of information being that it's total is 10 - none of the remaining numbers add up / total to 10 therefore Spooky's favourite number is 10 !
