How many females were surveyed?

Answer 1

Ok well A. is 25% males wanted to play sports
B. is 25% of the people wanted to read a book\
All you had to do was add, .10 + .15 = 25%
About 70% females were surveyed out of the 200 people.
.15 + .5 + .15 = .35
.35 * 200 = 70

Answer 2

a. The males who preferred playing sports were 0.30 of 200, which is 60.

b. The people who preferred reading a book are 0.10 + 0.15 = 0.25 of 200, which is 50.

c. The females who were surveyed were 0.15 + 0.05 + 0.15 = 0.35 of 200, which is 70.
