Question

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

a) 9
b) 16
c) 18
d) 32
e) 36

Difficulty: Low

ScottTargetTestPrep · Accepted Answer

We are given the following:
 
2 crowns = 3 shields
 
3 shields = 4 pounds

Thus, 2 crowns = 4 pounds. Now we can let x = the number crowns equal to 18 pounds and create the proportion:

2/4 = x/18

4x = 36

x = 9

Answer: A

You can do ratios:

2:3:4
4:6:8
8:12:16
9:13.5:18

where 18 pounds would equal 9 crowns

houston1980 · Answer

let c = crown; s=shield; AND p=pound;

2c=3s=4p

2c=4p

9c=18p

9 crowns = 18 punds

Hence   option A = 9    is the answer.

gmatzpractice · Answer

18/4 * 3 = 13.5 shields
2/3 = x/13.5
x=9 crowns
Answer A

dhruvin917 · Answer

The ratio is pretty simple here:
C : S : P --> 2 : 3 : 4

The question is, how many C's will equal 18p's. First find out how many P's are needed to get 18 based on our ratio:
18 / 4 = 4.5 --> this is going to be our multiple.

The ratio now is going to look like this:
2(x) : 4(x) --> 2(4.5) : 4(4.5) --> 9 : 18.

The answer is 9 or A

Solution

Let us write crown as C, shield as S and pound as P.

Given:

• 2C= 3S
• 3S= 4P

To find:

• We need to how many crowns equal 18P.

Approach and Working:

• 2C= 3S
• 3S= 4P
 o 2C= 4P or C= 2P
o Multiplying by 9, we get: 9C= 18 P

Hence, the correct answer is option A.

Answer: A

MsInvBanker · Answer

A 2 crowns are equal to 4 pounds (double the value), then 18 pounds will equal be 18/2 crowns. Thus, 9.
