Passage :
For the next four question that follow:
In a city, three daily newspapers A, B, C are published, 42% read A; 51% read B; 68% read C; 30% read A and B; 28% read B and C; 36% read A and C; 8% do not read any of the three newspapers.

Let x% people read all the three newspapers.
Since 8% people do not read any newspapers.
 (x – 24) + (x – 7) + (x + 4) + (30 – x) + (36 – x) + (28 – x) + x = 92
