in an examination 80%students passed in physics 70% in chemistry while 15% failed in both the subjects. if 3250 students passed in both the subjects. find the total number of students who appeared in examanitaion

5,000 students (hope this helps!)

Step-by-step explanation:

3250 students passed in both subjects

x is the percentage of students that passed in both subjects

total=100%

Passed students=100-15(failed students)=85

85 is the passed students so

passed students in both subjects x= 80+70-85=65

Now x=65

65% of total students=325

.°. Total students = 3250×100/65=5000

Ans. There were a total of 5000 students.

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
