OLD. NEW

H+W : S. S+W : H. H+W : S. W+S : H

2 : 1. 4 : 1. 2: 1. 8 : 7

Ratio equal

10: 5. 12:3. 10: 5. 8 : 7

H : W : S = 15. H : W : S= 15

3 : 7 : 5. 7 : 3 : 5

Answer 2

Answer:

Correct option is C - 57.1428%

Step-by-step explanation:

Initial Condition:

H+W:S = 2:1

S+W:H = 4:1

Now, let's multiply the ratios with 5 and 3

H+W:S = 10:5

S+W:H = 12:3

These two are now our new ratios

Final Condition:

H+W:S = 2:1

H:W+S = 7:8

Lets multiply equation 1 with 5 which gives us 10:5

Initial - W = 15-(3+5) = 7

Final - W = 15-(7+5) = 3

Decrease is 7-3 = 4

% Change =

$4 \div 7 \times 100$

= 57.1428%
