Question

Six dice are stacked as shown in the figure. On each dice, the sum of number appearing on a face and on the face opposite to it is $7$. What is the maximum possible sum of the numbers on the visible faces?

• A. $88$
• B. $89$
• C. $96$
• D. $147$

Answer 1

Answer: (B)

$89$

Sum of numbers on top dice = 20

Sum of number on left side dice in middle row = 13

Sum of number on right side dice in middle row = 13

Sum of numbers on left side dice in last row = 18

Sum of numbers on middle dice in last row = 7

Sum of numbers on right side dice in last row = 18

Total sum $=$ $20+13+!3+18+7+18$ $=89$

Hence, Option B is correct.
