Answer:

3180,795

Step-by-step explanation:

People liked to visit China [ ie.P(C)] = 40%

People liked to visit Europe [ie.P(E)] = 50%

People liked to visit America [ie.P(A)] = 60%

People liked to visit both China & America [ie.P(CnA)] = 25%

People liked to visit both America & Europe [ie.P(AnE) = 20%

People liked to visit both Europe & China [ie.P(EnC)] = 25%

Universal set 'U' us taken as 100

Hence P(AnCnE)=P(U) - P(A)-P(C)-P(E)+P(AnC)+P(CnE)+P(EnA)-10

=>> 100-(60+40+50)+(25+25+20)-10

=>> 100-150+70-10

=>> 10%

Therefore 318 is 10% of 'U'

=>> Total people asked = 10x/100=318

=>> 10x=31800

=>> x=3180

Total number of people asked =3180

People liked to travel to America only

=>> P(A)-P(AnC)-P(AnCnE)-P(AnE)

=>> 60-15-10-10

=>> 25%

= 25% of total liked to travel to America

=>> 3180×25%

=>> 795

Total number of people liked to travel to America =795

Hope it helps you...
