Question

A class of 40 students, in which 20% are girls, is planning a trip to Florida.50%of the boys and 25% of the girls wish to go Texas instead. What percentage of students wishes to leave for Florida?

Answer 1

Number of students : 40
20 percent are girl: ( 20/100) x40
= 8 girls
Then remaining are boys = 32

Among 8 girls 25% wishes to visit Texas = 2
Remaining 6 girls wishes to visit Florida.

Among 32 boys 50% wishes to visit Texas = 16
Remaining 16 boys wishes to visit Florida.

Therefore, total students wishes to visit Texas
= 16 + 2 = 18
Total % = (18/40) x100
= 45%

Therefore, remaining 55% of students visited Florida.
