Data Interpretation - Pie Charts - Discussion

Study the following pie-diagrams carefully and answer the questions given below it:

Percentage Composition of Human Body

1. 

What percent of the total weight of human body is equivalent to the weight of the proteins in skin in human body?

[A]. 0.016
[B]. 1.6
[C]. 0.16
[D]. Data inadequate

Answer: Option B

Explanation:

Let the body weight be x kg.

Then, weight of skin protein in the body
= [ 16% of ( 1 of x ) ] kg
10
= ( 16 x ) kg.
1000

Therefore Required percentage = [
( 16x )
1000
x 100 ] % = 1.6%.
x

Both the compositions are given for the entire body. How can we find the composition in an individual component. The answer should be data inadequate.

The answer should be data inadequate as the fraction of proteins in boned has not been provides in the question.

Proteins, 16% in 100% = 0.16%.

Skin 1/10*100= 10%.

Proteins in skin= 0.16% * 10% =1.6%.

Wt of proteins = 16%.

Wt of Skin = 1/10. converting in to %value => 1/10*100 = 10%.

Wt of proteins in skin = 16% * 10%.

Human body Wt = 100%.

=>(16*10)/100 = 1.6%.

Put most simply: 1/10 = 0.1.

16% of 0.1 = (0.1 * 0.16) = 0.016.

As a percentage: 0.016 * 100 = 1.6%.

Assuming that water, proteins and other dry elements are uniformly distributed across various body parts given in the 1st pie chart. It should be mentioned in the question.

X% = 16% * 1/10.
X/100 = (16/100) * (1/10).
X = 16/10.
X = 1.6.

Yes, I agree @Trishul.

How 1000 came? Please explain.

Assuming that who make this question have 70% water in his brain.
