Six numbers 21, 22, 23, 24, 25 and 26 are written on different faces of a dice. Three positions of this dice are shown in the figure. Find the number on the face opposite to 24.

Option
a) 26
b) 25
c) 22
d) 21

1 and 2 dice both have 25 and 21
So 22 will come opposite to 23
2 and 3 dice both have 25 and 22
So 21 will come opposite to 24

Correct Answer: d) 21
