Q. if R is an integer, is R evenly divisible by 3

1. 2R is evenly divisible by 3

2. 3R is evenly divisible by 3

Statement 1: 2R is evenly divisible by 3

Since 2 is not a multiple of 3, hence # should be a multiple of 3

Sufficient

Statement 2: 3R is evenly divisible by 3

Since 3 is a multiple of 3, R may or may not be a multiple of 3

Case 1: R = 2, 3R = 6. Here R is not a multiple of 3.

Case 2: R = 3, 3R = 9. Here R is a multiple of 3.

Insufficient

Correct option: A
