# Quantitative Aptitude: Data Interpretation Questions Set 49

Directions(1-5): The table shows the number of people staying in five different localities and the percentage-wise breakup of Men,Women and Children. Study the table carefully and answer the related questions.

1. If 20% of the men staying in locality D are working in Infosys and the 40% of the women staying in locality B are working in HCL, then what is the difference between the number of men staying in locality D who are working in Infosys and the number of women staying in locality B who are working in HCL?

B)Â 1300
C)1000
D)1400
E) 800
Â Â Option D
Solution:
Number of men staying in locality D who are working in Infosys = 12000*(35/100)*(20/100) = 840
Number of women staying in locality B who are working in HCL = 16000*(35/100)*(40/100) = 2240
Required difference = 2240 â€“ 840 = 1400
2. Number of children staying in localities A and B together is approximately what percent of the number of children staying in localities D & E together?

Â Â Option B
Solution:
Number of self-employed men staying in locality A = 18000*(45/100)*(40/100) = 3240
Number of women staying in locality B = 16000*(35/100) = 5600
Required % = (3240/5600)*100 = 57.86%= 58%(approx.)

= 240+896+1512+192+288+78 = 3206
Total number of defective phones by D in all the years = 41000*(2.3/100)+ 28500*(3/100)+ 27500*(2/100)+ 24500*(1/100)+ 32800*(3.5/100)+ 17800*(1.5/100)
=943+855+550+245+1148+267 = 4008

is there any difference between mind & brain ????

The Mind is the source of all human actions, yet the body is given more importance.
Assumptions:
I. The Mind is not given proper importance.
II. The Body is getting undeserved importance.
III. Every action starts from the brain.
Only I
Only 2
Only II and III
Only III
Reattempted
All of them

sol ; only 1
l is implicit, as the statement shows that importance is not being given where it has to be given. ll is not implicit as it is not known from the statement whether the importance given to body is deserved or not. 3 is not implicit, as it is out of context. There’s a difference between the brain and the mind. One should not confuse the two.
