Answer / sarat
500 = Total+50
Total(450) = only one paper(p) + 29+20+35 + all three (g)
285+212+127 = p + 2( 29+20+35 )+ 3g
solve above .. to get g = 45 ...

hindu and
times of India and 29 read ONLY hindu and Indian express
and 35

Answer / sarvani
The data is incorrect.
coz.
(^==>intersection & U==> union)
n(a^b^c)=n(A)+n(b)+n(c)-n(a^b)-n(b^c)-n(a^c)+n(a^b^c)
a=hindu
b=express
c=times assume
the formula fails
companies give this blunder without knowing simple basics

Answer / sidhant
The answer is 45 people read all the three news papers and 321 people read only one news paper. Just draw a venn diagram with three circles and mark the corresponding parts using the given data. If you take the intersection part of all the 3 circles as 'x'. three expressios are formed as follows: 285-(20+29+x),212-(29+35+x) and 127-(20+35+x).these equations will giv people reading hindu,indian exp and times of india respectively. add (20+29+35+x) and 285-(20+29+x),212-(29+35+x) and 127-(20+35+x) and equate it to 450. x gives the intersection of 3 circles. then u can find individual readers by sybstituting in the expressions 285-(20+29+x),212-(29+35+x) and 127-(20+35+x).
