the sum of all two digit numbers divisible by 5 is Choose the correct choice from the following options
A) 945	B) 3487	C) 28	D) 279	E) 1287
Required numbers are 10,15,20,25,...,95   This is an A.P. in which a=10,d=5 and l=95.   Let the number of terms in it be n.Then t=95   So a+(n-1)d=95.   10+(n-1)*5=95,then n=18.   Required sum=n/2(a+l)=18/2(10+95)=945.   945nswer: 945) 945
