Question

In a certain game, the units of currency of three countries are the crown, the shield, and the pound, respectively. If 2 crowns equal 3 shields and 3 shields equal 4 pounds, how many crowns equal 18 pounds?

Answer 1

9 crowns

Explanation:

Given,

2 crowns = 3 shields,

Now, 3 shields = 4 pounds

⇒ 2 crowns = 4 pounds

`\implies 1\text{ pound}=(2)/(4)=(1)/(2)\text{ crown}`

`\because 18\text{ pounds}=18* \text{ 1 pounds}`

`\implies 18\text{ pounds}=18* (1)/(2)\text{ crown}=9\text{ crowns}`

Hence, there would be 9 crowns in 18 pounds.
