Directions (1-5): Study the following pie-diagrams carefully and answer the questions given below it:
Percentage Composition of Human Body

### Q1

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. 0.0016

B
Let the body weight be x kg
Then, weight of skin protein in the body = [16% of ($\frac {1}{10}$ of x)] kg
= ($\frac {16}{1000} x$) kg
i.e, Required percentage = [$\frac {(\frac {16 x}{1000})}{x} \times 100$ % = 1.6%

### Q2

What will be the quantity of water in the body of a person weighing 50 kg?
A. 20 kg B. 35 kg C. 41 kg D. 42.5 kg

B
Quantity of water in the body of a person weighing 50 kg = (70% of 50) kg = 35 kg.

### Q3

What is the ratio of the distribution of proteins in the muscles to that of the distribution of proteins in the bones?
A. 1 : 18 B. 1 : 2 C. 2 : 1 D. 18 : 1

C
Required ratio = $\frac {16% of \frac {1}{3}}{16% of \frac {1}{6}} = \frac {6}{3} = \frac {2}{1}$

### Q4

To show the distribution of proteins and other dry elements in the human body, the arc of the circle should subtend at the centre an angle of:
A. 54° B. 126° C. 108° D. 252°

C
Percentage of proteins and other dry elements in the body = (16% + 14%) = 30%.
Therefore Central angle corresponding to proteins and other dry elements together
= 30% of 360°
= 108°.

### Q5

In the human body, what part is made of neither bones nor skin?
A. $\frac {1}{40}$ B. $\frac {3}{80}$ C. $\frac {2}{5}$ D. None of these

D
Part of the body made of neither bones nor skin = 1 - ($\frac {1}{6} + \frac {1}{10} = \frac {11}{15}$)
