There are 76 persons. 53 can read hindu,46 can read times,39 can read deccan and 15 can read all.if 22 can read hindu and deccan and 23 can read deccan and times then what is the number of persons who read only times and hindu
n(H u T u D) = n(H) + n(T) + n(D) + n(H n T n D) - n(H n D) - n( T n D) - n(H n T)
--> 76 = 53+46+39+15 - 22 - 23 - x
--> 76 = 153 - 55 - x
--> x = 153 - 131
--> x = 22.
So, number of people who can read only Hindu and Times is 22.
