the third time?
(A) 17 (B) 18
(C) 19 (D) 20 (E) 22
Please answer and let me know why that answer, thank you!

Answer 1

B. 18

Explanation:

Her first two arrows landed on the same circle with 14 points. This means that 1 arrow in that circle = 7 points.

The second time, one arrow landed on the circle that carry 7 points per arrow, and the next inner circle would carry = 16 - 7 = 9 points

Therefore, if in her third throw, the two arrows landed in the inner circle that has 1 arrow recording 9 points, she would get = 9*2 = 18 points
