Return of Portfolio=10.9%
Return of Benchmark=7.6%
Return of Market=9.4%
Analysis
Return due to active mgmt=P-B=10.9-7.6=3.3%
Return due to style=B-M=7.6-9.4=-1.8%
Return due to skill=???
Anybody care to join
I would say Return to skill (not style) = P-M thus same as (Return to active mngmt + Return to style) = 10,9% - 9,4% = 1,5 % or 3,3 % + (-1,8%) = 1,5 %.
PS
Take it with reserve but I enjoy solving such rebus questions.
