In town of 500 people, 285 read Hindu and 212 read Indian express, 127 read Times of India, 20 read Hindu and times of India, 29 read Hindu and Indian express and 35 read times of India and Indian express. 50 read no news paper. Then how many read only one paper?

• let,
  H,TOI,AND IE ALL ARE=x
  so,only hindu=285-20-29-x
  =236-x
  only TOI=127-20-35-x
  =72-x
  only IE=212-35-29-x
  =148-x
  NOW;
  236-x+72-x+148-x+20+29+35+x+50=500
  590-2x=500
  x=45
  this value who read all the 3 daily
  BUT que is find only one read;
  So,
  = 236-45+72-45+148-45
  =191+27+103
  =321
  This is the final answer
  Solve This Que using venn diagram

• 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.

• 2. X=1paper reader
  y=all 3 paper reader
  500-50=x+y+29+20+35
  x+y=366
  Again 285+212+127=x+2(29+20+35)+3y
  X+3y=456
  Solve for x andy,x=321,y=45

• ans: 456
  prof: h i
  (285-20-29=236) 29 (212-29-35=148)
  20 35
  t(127-20-35=72)
  peope who read only hindu=285 ; peope who read only times=72 ;peope who read indian=148 total = 285+72+148 = 456

• using van diagram method,
  Let, x no of people read all 3 papers,
  500-50=285+212+127-(20+x)-(29+x)-(35+x)+x
  => x=45,
  
  so , the no of people read only one paper is=
  285-(20+29+45)+212-(29+35+45)+127-(20+35+45)=321 (Ans..)

• The part of tank filled by Pipe A in 1 min = 1/20
  The part of tank filled by Pipe B in 1 min = 1/30
  The part of tank emptied by Pipe C in 1 min = 1/15
  The part of tank filled in 1 min is 1/20 + 1/30 - 1/15 = 1/60
  
  The total time taken to fill the tank is 60 min = 1 hr.
