In a class, 20% students read mathematics,16% read physics and 10% read both the subjects. If there are 50 students in the class, then the number of students in the class who read either mathematics or physics is

In a class 20 students read mathematics, 16 read physics and 10 read both the subjects. The number of students in the class who read either mathematics or physics is (A) 20 (B) 16 (C) 10 (n) 26

In a class, 30% of the students offered mathematics, 20% offered chemistry and 10% offered both. If a student is selected at random, find the probability that he has offered mathematics or chemistry.

In a class of 100 students,60 like Mathematics,72 like Physics,68 like Chemistry and no student likes all three subjects.Then number of students who don't like Mathematics and Chemistry is

In a class of 50 students 32 likes Mathematics , 24 like Science and 12 like both . Find the number of students who like neither of the two subjects.

There are 20 students in a chemistry class and 30 students in a physics class. If ten students are to be enrolled in both the courses, then the number of students which are either in physics class or chemistry class is

In the examination of Mathematics and Physics,15% students failed in Physics and 75% students passed in both the subjects.If 120 students passed only in Physics,then the total number of students who took this examination is k then (k)/(150) is (A) 6 (B) 7 (C) 8 (D) 9

Read the following information carefully and answer the questions given below- 1000 students appeared in an examination Out of which 275 students passed in physics, 320 students passed in chemistry and 350 students passed in mathematics. 84 students passed in both chemistry and mathematics 60 students passed in both physics and mathematics, 50 students passed in both physics and chemistry and 34 students passed in all the three subjects. What is the ratio of students passed in physics and mathematics to the number of students passed in physics and chemistry?
