A) 86	B) 94
C) 100	D) 115

Answer & Explanation Answer: C) 100

Q:

The sum of all two digit numbers divisible by 5 is

A) 945	B) 678
C) 439	D) 568

Answer & Explanation Answer: A) 945

Explanation:

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.
