406 is the answer.draw the venn diagram and subtract all the the intersections from individuals u get 456.Now sub 456-50=406 as 50 mem dont read any of the paper.

The values are not right. The formula is

n(A U B U C) = n(A) + n(B) + n(C) - n(A n B) - n (A n C) - n(B n C) + n (A n B n C).

When we substitute the values in this, we get

450 = 285 + 212 + 127 - 20 - 29 - 35 + x

450 = 540 + x

which is impossible.......please check back with the values.

Hello Everybody,HIndu = 285TOI = 127IE = 212now H nd TOI both is = 20(Draw a Venn Diagram nd check all) . TOI nd IE both is = 35H nd IE both is = 29now suppose H , TOI nd IE all is = x ;so,only Hindu is = 285-20-29-x = 236-x ;only TOI is = 127-20-35-x = 72-x ;only IE is = 212-35-29-x = 148-x ;now, 236-x + 72-x + 148-x + 20 + 29 + 35 + x + 50 = 500 590 -2x = 500 so, x = 45this is the value who read all the 3 dailies.so,result is = 236-45 + 72-45 + 148-45 = 191 + 27 + 103 = 321.this is the final result...you all plz check it...this answer is based on Venn Diagram.Thanks nd all the bestChandan Sinha

Ans : 366

Just add how many persons read two papers (20+29+34)

and in 500 peoples, 50 persons didnt read any news papers
so just deduct from 500 (hence 450 peoples only read news papers in that town)

finally deduct the no. of persons read two papers from 450 is the answer(i.e., 366)

Here they did not mentioned like the people reads only 2, the people who read 3 also belonging to the category of reading 2 papers, so we don't want to assume x because it is already included in the category of reading two papers. So as per my view the solution is derived here
the people only reads Hindhu=285-(20+29)=236
IE=212-(29+35)=158
TOI=125-(20+35)=70
 236+158+70-50= 404
