The answer is C. 51.
Here’s how to solve it:
Row 1
Crown + Crown + Crown = 24
Therefore, one crown is
24 ÷ 3 = 8
Row 2
Crown + Ring + Ring = 18
Since the crown is 8,
8 + Ring + Ring = 18
Two rings are 10.
Therefore, one ring is 5
Row 3
Ring + Gem + Gem = 11
Since the ring is 5,
5 + Gem + Gem = 11
Two gems are 6.
Therefore, one gem is 3
Last equation
Gem + Crown × 2 Gems = ?
The important thing here is that the last equation has 2 gems.
Since one gem is 3, 2 gems is 6.
Also, multiplication comes first in calculations.
Therefore,
3 + 8 × 6
= 3 + 48
= 51
So the answer is C. 51.
