KatRina [158]

Answer:

3

Step-by-step explanation:

It is a well known trick that when you add together the digits of a number, if they are a multiple of 3 then the number is divisible by 3. Let's go through the options and check them:

7+5+7+0=19 not a multiple of 3

7+5+7+1=20 not a multiple of 3

7+5+7+2=21 multiple of 3

7+5+7+3=22 not a multiple of 3

7+5+7+4=23 not a multiple of 3

7+5+7+5=24 multiple of 3

7+5+7+6=25 not a multiple of 3

7+5+7+7=26 not a multiple of 3

7+5+7+8=27 multiple of 3

7+5+7+9=28 not a multiple of 3

As you can see, only 3 of these were possibilities that satisified the conditions. Hope this helps!

= 5400 + 120 + 30

= 5550
