Answer:
14.85%
Step-by-step explanation:
let total be 100 parts
out. 100
/. \
25%. 75%
25% were sail boats
75% were non sailboats
in 75% of non sailboats 3/5 are new
75*3/5= 45 % are new boats
33% out of total ie 100 boats are used
so ratio of sailboats : non sailboats
25:75ie 1:3 = 33 %
ie 4parts = 33 ie 1 part = 33/4 = 8.25
100
/. \
8.25. 3*8.25 = 24.75
in 24.75 the new one are 24.75*3/5 = 14.85 %
