The pie chart shows the distribution of 600 mathematics textbooks for Arts, Business, Science and Technical Classes. How many textbooks are for the technical class?
100
150
200
250
Correct answer is D
Arts = 90o business = 75o, science = 45o
Technical 360o - (90o - 75o + 45o) = 360o - 210o
Technical = 150o
textbooks for technical class = \(\frac{150^o}{360^o}\) x 600
= 250
