Which of the following rows/columns are connected/related with each other in some way?
Table (rows 1-5; columns I, II, III, IV, V):
Row 1: I 10, II 24, III 6, IV 18, V 42
Row 2: I 16, II 26, III 8, IV 24, V 56
Row 3: I 15, II 27, III 5, IV 15, V 35
Row 4: I 18, II 36, III 9, IV 27, V 63
Row 5: I 20, II 40, III 10, IV 30, V 70
Answer: C
In every row, column IV equals 3 times column III (6 to 18, 8 to 24, 5 to 15, 9 to 27, 10 to 30) and column V equals 7 times column III (6 to 42, 8 to 56, 5 to 35, 9 to 63, 10 to 70). So columns III, IV and V are related. Columns I and II do not follow this rule with the others. Option C is correct. Option C.
