Each of the letters in the table above represents one of the numbers 1, 2, or 3, and each of these numbers occurs exactly once in each row and exactly once in each column. What is the value of r?

(1) v + z = 6

(2) s + t + u + x = 6

For St 1, we are given that v+z=6...since possible nos are only 1,2 and 3, we can conclude that v=z=3. Since v and z are in row 2 and row 3 then number 3 in row 1 has to be at position of r -----> r= 3.

Cancelling option B, C and E

From st 2, we have s+t+u+x= 6 and 2r+s+u+t+x= 12....solving for r we get r--->3

Hence ans should be D
