I think its 210 because there are 7 letters and 3 vowels so the permutation would be 7 P 3.
One number be x
x+(x+1)+(x+2)=63
x+x+1+x+2=63
3x+3=63
3x=63-3
3x=60
x=60:3
x=20
smallest number = x=20
middle <span>number = x+1= 20+1=21
</span>largest<span><span><span> number = x+2</span> =20+2= 22</span>
</span>
B. Annually 2 years would equal 9%. 540/2=270.
3,000x9%=270.
Altogether would be 18%. But, if we’re solving it for each separate year, then it would be 9%.
The answer is c to your question
