D
分析:根據(jù)奇數(shù)和偶數(shù)的性質(zhì):奇數(shù)+奇數(shù)=偶數(shù),奇數(shù)-奇數(shù)=偶數(shù),奇數(shù)+偶數(shù)=奇數(shù),奇數(shù)-偶數(shù)=奇數(shù),偶數(shù)-偶數(shù)=偶數(shù);據(jù)此解答.
解答:A、237892是偶數(shù),46051是奇數(shù),根據(jù)奇數(shù)+偶數(shù)=奇數(shù)可知:237892+46051的和是奇數(shù);
B、856743是奇數(shù),234086是偶數(shù),根據(jù)奇數(shù)-偶數(shù)=奇數(shù)可知:856743-234086的差是奇數(shù);
C、11+13+15+17+19,這五個數(shù)都是奇數(shù),根據(jù)奇數(shù)+奇數(shù)=偶數(shù),偶數(shù)+偶數(shù)=偶數(shù),奇數(shù)+偶數(shù)=奇數(shù),所以最后的和是奇數(shù);
D、100-7-5-3-1=100-(7+5+3+1)=100-16,根據(jù)偶數(shù)-偶數(shù)=偶數(shù)可知:最后的得數(shù)是偶數(shù);
故選:D.
點評:此題考查的是奇數(shù)和偶數(shù)的性質(zhì),根據(jù)其性質(zhì)進(jìn)行分析即可.
