Let f:[0,1]×R2R be function satisfying Caratheodory's conditions and e(t)L1[0,1]. Let η(0,1), ξi(0,1), ai0, i=1,2,,m2, with i=1m2ai=1, 0<ξ1<ξ2<<ξm2<1 be given. This paper is concerned with the problem of existence of a solution for the following boundary value problems x(t)=f(t,x(t),x(t))+e(t),0<t<1,x(0)=0,x(1)=x(η),x(t)=f(t,x(t),x(t))+e(t),0<t<1,x(0)=0,x(1)=i=1m2aix(ξi).

Conditions for the existence of a solution for the above boundary value problems are given using Leray Schauder Continuation theorem.
