Evenly Divisible ??

by jainpiyushjain » Thu Mar 07, 2013 7:11 pm
Q. if R is an integer, is R evenly divisible by 3
A. 2R is evenly divisible by 3
B. 3R is evenly divisible by 3

Source: Kaplan Strategy Guide

I rephrased the question;
When R is divided by 3 is the quotient an even number ? In other words Is R divisible by 6 ?

However the book said to be "evenly divisible by 3" is to be multiple of 3.

Please clarify. Thank you

u rephrasing is wrong !!
when u say something is evenly divisible by some other thing .u simply mean whether this something is multiple of this other thing

evenly divisible means equally distributed : 3 books can be equally distributed in among 3 boys !! right ?

In simple words, "evenly divisible" means 'divisible'.

Statement 1: 2R is divisible by 3.
As 2 is not a multiple of 3, R must be a multiple of 3.

Sufficient

Statement 2: 3R is divisible by 3.
As 3 is a multiple of 3, R may or may not be a multiple of 3.

Not sufficient

The correct answer is A.
