The sum of 3 scores is 231. The first is 20 more than the second. The sum of the first two is 6 more than twice the third.

Question

What is A

Answer 1

Let the second score be x

First score will be x+20

The third score will be 1/2(x+20+x+6)=1/2(2x+26)=x+13

x+x+20+x+13=231

3x+33=231

3x=198

x=66

The scores are 86,66 and 79 respectively.
