2/5
D
None of these
Correct Answer: Option D

Part of the body made of neither bones nor skin

= 1 - (1+1)=11.61015

A
1 : 18
B
1 : 2
C
2 : 1
D
18 : 1
Correct Answer: Option C
Required ratio =

Question 4
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
Correct Answer: Option B

Let the body weight be x kg.

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











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

Question 5
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
54º
B
126º
C
108º
D
252º
Correct Answer: Option C

Percentage of proteins and other dry elements in the body

=(16% + 14%)

= 30%

Central angle corresponding to proteins and other dry elements together

= 30% of 360º

= 108º.
