Question: 716

11. Images

With the exception of the shaded squares in the first row and first column, every square in the table above is to be filled in with a number equal to the sum of the number directly above it and the number directly to its left. For instance, the number 7 in the second row is the sum of 3 in the square above it and 4 in the square directly to its left. What is the value of x?

  • A. 16
  • B. 84
  • C. 96
  • D. 112

Correct Answer: D

Explanation:

D

Data Analysis (tables) MEDIUM-HARD

Although we don't need to fill in the entire table, it's interesting to note that it has a "diagonal symmetry" when it is completed. Just following the rule and moving systematically toward x reveals that it is 56 + 56 = 112.
