答案解析

A项，由图1条形图可知，2015年有22．4万所幼儿园，2010年有15．0万所幼儿园，平均每年增加(22．4—15．0)÷(2015—2010)=7．4÷5<10÷5=2万所。A项说法错误。
B项，由图2条形图可知，2017年公办幼儿园在园幼儿数(2027．8万人)>2018年公办幼儿园在园幼儿数(2016．4万人)，不是逐年增加。B项说法错误。
C项，从文字材料可知，2018年公办幼儿园数为10．1万所，缺少2010年公办幼儿园数的相关数据，无法计算其年均增长率，无法推出C项。
D项，根据图2注可知，公办幼儿园在园幼儿比=公办幼儿园在园幼儿人数÷在园幼儿总人数，则在园幼儿总人数=公办幼儿园在园幼儿人数÷公办幼儿园在园幼儿比。2015年公办幼儿园在园幼儿人数为1962．4万人，在园幼儿比为46．0％，则2015年在园幼儿总人数为1962．4÷46．0％。根据文字材料可知，2018年幼儿园在园幼儿人数为4656．4万人。所求为

能够推出D项。
