Thank you very much!!

Females (this yr) = 130% of Females (last yr)

Males (this yr) = Females (this yr)

Therefore,

120% of Males (last yr) = 130% of Females (last yr)

100% of Males (last yr) = 108 1/3 % of Females (last yr)

Males (last yr) + Females (last yr) = 375

108 1/3 % of Females (last yr) + 100% of Females (last yr) = 375

208 1/3 % of Females (last yr) = 375

30% of Females (last yr) = 54
