HIndu = 285
TOI = 127
IE = 212
now H nd TOI both is = 20(Draw a Venn Diagram nd check all)
. TOI nd IE both is = 35
H nd IE both is = 29
now 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.
