Answer:
Step-by-step explanation:
<u>Two-digit numbers are:</u>
<u>Sum of them is:</u>
- 10a + b + 10a + c + 10b + a + 10b + c + 10c + a + 10c + b = 528
- 22a + 22b + 22c = 528
- a + b + c = 528/22
- a + b + c = 24
The only option of three different digits with the sum of 24 is 7, 8 and 9
Set up as a proportion
90/6 = 300/x
multiply 90x=6(300)
90x = 1800
divide both sides by 90
x=20
