Question: If the odd numbered dice have even number of dots on their top faces, then what would be the total number of dots on the top faces of their dice?
[A].

8

[B].

10

[C].

12

[D].

14

Answer: Option A

Explanation:

Odd numbered dice are : (II), (III) and (V)

No. of dots on the top faces of these dice are 2, 2 and 4 respectively.

Required total = 2 + 2 + 4 = 8

If even numbered dice have even number of dots on their top faces, then what would be the total number of dots on the top faces of their dice?

by
Question: If even numbered dice have even number of dots on their top faces, then what would be the total number of dots on the top faces of their dice?
[A].

12

[B].

14

[C].

18

[D].

24

Answer: Option C

Explanation:

Even numbered dice are: (II), (IV) and (VI)

No. of dots on the top face of (II) dice = 6

No. of dots on the top face of (IV) dice = 6

and No. of dots on the top face of (VI) dice = 6

Therefore Required total = 6 + 6 + 6 = 18
