Reasoning – Scoring ring – Possible scores!

QNR 5. Kavi fires three arrows. Each one hits a scoring ring. Which one of the following total is not possible?

1) 17

2) 18

3) 21

4) 22

Ans:- This is a simple question; faster way to solve this should be to observe the options:

17 = 4 + 4 + 9

21 = 18 + 3 = 3 + 9 + 9

22= 18 + 4 = 4 + 9 + 9

Only 18 cannot be put as possible sum of any combination. Option 2.
