Say Casey's score for first 9 holes be a and next nine holes be b

1) b-a =13 , not sufficient
2) 2b -a = 58, not sufficient

Combining, 2 equations in 2 variables, can solve, Hence C

let score of first nine goals be x and that for last nine be y
hence
s1) y-x=13
insuff
s2)2y-x=58
insuff

s1)+s2)=we can get x and y
totaling gives the ans hence C

St.1 L-F = 13/...... but that is not suff. to calculate the total..
St.2 2L - F= 58 ... again insuff.
combine..) adding above two 3L= 71 its coming in fraction ( I donno score is applicable or not )
if applicable
L= 71/3, F= 71/3-3 = 62/3
total = (71+62)/3 = 133/3 suff...AnsC
