What's my number? When you divide my number by 5, the remainder is 4. My number has two even digits. The sum of the digits is 10.

Question

My daughters homework problem has me stumped.

Answer 1

The sum of the digits = 10, and that the number has 2 even digits are your first clues.

Possibilities for the number ab = 10, where a = 1st digit, and b = 2nd digit are

 

ab = 28

ab = 46

ab = 64

ab = 82

 

These are the only possibilities given the restriction that the number have 2 even digits = 10

 

Dividing by 5 we find (64 ÷ 5) = 60 + 4 is the only number which satisfies the 1 st condition, 

 

so your number is 64
