Statement 1. The distance between r and 0 is 3 times the distance between m and 0.
r = 3m or -3m.
Since we don’t know the distance of ‘m’ from 0, we can’t find the value of ‘r’.
Hence, Insufficient.
Statement 2. 12 is halfway between m and r. This gives, m + r = 2 x 12 = 24
(m, r) could be ( 11,13), (10,14),(9,15)……….
Hence, Insufficient.
Statement 1 & 2 toghether. Combining the results of statement 1 & 2, we get
m + 3m = 24 i.e. m = 6 and r = 18
m – 3m = 24 i.e. m = -12 and r = 36. Hence, Insufficient.
