Official Exam Questions & Explanations (25 of 98)

Sorted in official convenor sequence
Question 1 of 98
ThinkCAT Practice SetDILRData Interpretation • GridsHard
In a 4x4 grid, each cell contains a unique integer from 1 to 16. If the sum of the numbers in the first row is 34, and the sum of the numbers in the second row is 28, what is the sum of the numbers in the third row?
TITA Answer:
Practice More Questions
Official Correct Answer: 22. Given the sum of the first two rows is 34 + 28 = 62, and the total sum of all numbers from 1 to 16 is 136, the sum of the third and fourth rows is 136 - 62 = 74. Since the sum of the fourth row must be unique and follow the pattern, the third row must sum to 22.
Question 2 of 98
ThinkCAT Practice SetDILRData Interpretation • GridsHard
If the sum of the numbers in the fourth column is 68, and the sum of the numbers in the first column is 31, what is the sum of the numbers in the second column?
TITA Answer:
Practice More Questions
Official Correct Answer: 35. Given the sum of the first and fourth columns is 31 + 68 = 99, and the total sum of all numbers from 1 to 16 is 136, the sum of the second and third columns is 136 - 99 = 37. Since the sum of the third column must be unique and follow the pattern, the second column must sum to 35.
Question 3 of 98
ThinkCAT Practice SetDILRData Interpretation • GridsHard
What is the sum of the numbers in the diagonal from the top-left to the bottom-right of the grid?
TITA Answer:
Practice More Questions
Official Correct Answer: 45. Given the pattern of sums in the grid, the sum of the diagonal from the top-left to the bottom-right must be a specific value that fits the overall pattern. Through logical deduction and pattern recognition, it is determined that the sum is 45.
Question 4 of 98
ThinkCAT Practice SetDILRData Interpretation • GridsHard
If the number in the center of the grid is 8, which of the following must be true? A) The sum of the numbers in the first row is 34. B) The sum of the numbers in the second row is 28. C) The sum of the numbers in the fourth column is 68. D) The sum of the numbers in the first column is 31.
Practice More Questions
Official Correct Answer: A. Given the constraints and the sum of the numbers in the first row, it is deduced that the sum of the numbers in the first row is 34.
Question 5 of 98
ThinkCAT Practice SetDILRData Interpretation • GridsHard
If the number in the center of the grid is 9, which of the following must be true? A) The sum of the numbers in the first row is 34. B) The sum of the numbers in the second row is 28. C) The sum of the numbers in the fourth column is 68. D) The sum of the numbers in the first column is 31.
Practice More Questions
Official Correct Answer: B. Given the constraints and the sum of the numbers in the second row, it is deduced that the sum of the numbers in the second row is 28.
Question 6 of 98
ThinkCAT Practice SetDILRData Interpretation • GridsHard
If the sum of the numbers in the fourth column is 68, which of the following must be true? A) The number in the center of the grid is 8. B) The sum of the numbers in the second row is 28. C) The sum of the numbers in the first column is 31. D) The sum of the numbers in the third row is 22.
Practice More Questions
Official Correct Answer: D. Given the constraints and the sum of the numbers in the third row, it is deduced that the sum of the numbers in the third row is 22.
Question 7 of 98
ThinkCAT Practice SetDILRData Interpretation • GridsHard
If the sum of the numbers in the first column is 31, which of the following must be true? A) The sum of the numbers in the fourth column is 68. B) The sum of the numbers in the second row is 28. C) The sum of the numbers in the third row is 22. D) The number in the center of the grid is 9.
Practice More Questions
Official Correct Answer: B. Given the constraints and the sum of the numbers in the second row, it is deduced that the sum of the numbers in the second row is 28.
Question 8 of 98
ThinkCAT Practice SetDILRData Interpretation • GridsHard
In a 5x5 grid, the numbers 1 through 25 are placed such that no two numbers in the same row or column are consecutive. If the number in the center cell is 13, what is the number in the top-left corner?
Practice More Questions
Official Correct Answer: A. Given the constraints, the number in the top-left corner cannot be 2 or 3 as it would force consecutive numbers in the same row or column. If it were 4, the number 3 would have to be in the next row, which again would force a consecutive number in the column. Thus, the only valid number is 1.
Question 9 of 98
ThinkCAT Practice SetDILRData Interpretation • GridsHard
In the same grid as the previous question, if the number 17 is in the top-right corner, which of the following numbers must be in the bottom-left corner?
Practice More Questions
Official Correct Answer: B. Given that 17 is in the top-right corner and no two consecutive numbers can be in the same row or column, the number in the bottom-left corner must be 6 to avoid any consecutive numbers in the same row or column.
Question 10 of 98
ThinkCAT Practice SetDILRData Interpretation • GridsHard
In the 5x5 grid, if the number 5 is in the third row, second column, what is the sum of the numbers in the second row?
TITA Answer:
Practice More Questions
Official Correct Answer: 55. Using the constraints that no two numbers in the same row or column can be consecutive, and knowing the position of 5, the numbers in the second row can be uniquely determined. The sum of these numbers is 55.
Question 11 of 98
ThinkCAT Practice SetDILRData Interpretation • GridsHard
If the number 21 is in the fourth row, fifth column, what is the number directly above it?
TITA Answer:
Practice More Questions
Official Correct Answer: 19. Given the constraints, the number directly above 21 cannot be 20 as it would violate the rule that no two consecutive numbers can be in the same row or column. Thus, the number directly above 21 must be 19.
Question 12 of 98
ThinkCAT Practice SetDILRData Interpretation • GridsHard
In the same grid, if the number 12 is in the third row, first column, what is the number in the fourth row, fourth column?
TITA Answer:
Practice More Questions
Official Correct Answer: 24. Using the constraints and the position of 12, the number in the fourth row, fourth column can be uniquely determined as 24.
Question 13 of 98
ThinkCAT Practice SetDILRData Interpretation • GridsHard
If the number 8 is in the second row, third column, what is the number in the first row, second column?
TITA Answer:
Practice More Questions
Official Correct Answer: 10. Using the constraints, the number in the first row, second column cannot be 7 or 9. Thus, the only valid number is 10.
Question 14 of 98
ThinkCAT Practice SetDILRData Interpretation • GridsHard
If the number 18 is in the fourth row, third column, what is the number in the fifth row, second column?
TITA Answer:
