in a survey of 120 people it was found that 65 people like Messi and 60 like Ronaldo while 20 donot like both. by drawing Venn diagram find the number of people who like both Messi and Ronaldo

15.

(P.S: Messi is the greatest footballer of all time) :)

To get the number of people who like both Messi and Ronaldo, you will add the two figures and the remain 20 that is not in the box minus x =120

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
