Chemistry vs Maths महा-संग्राम

There are 175 students in a class, out of which 100 students opt Maths, 70 opt Physics and, 23 opt Physics and Chemisty, 28 opt Chemistry and Maths and 18 opt of all three subjects. Now find each of the following : No. of students who opt why only Maths (ii) No. of students who opt only Physics (iii) No. of students who opt only Chemistry (iv) No. of students who opt Physics and Chemisty but not Maths (v) No. of students who opt Maths and Physics but not Chemistry (vi) No. of students who opt only one subject (viii) No. of students who opt atleast one subject (viii) No. of student who do not opt any subject.

In a survey of xavirs's school of Bhubaneswar of 200 students, It was found that 120 study math, 90 study physics, 70 study shemistry, 40 study math and physics, 30 study physics and chemistry, 50 study chemistry and math and 20 study none of these subjects then the number of students study all the subjects is :

Read the information given below and answer the questions that follow. The result of an exam is given below. Out of 1000 students who appeared (i) 658 failed in Physics (ii) 166 failed in Physics and Chemistry (iii) 372 failed in Chemistry, 434 failed in Physics and Maths (iv) 590 failed in Maths, 126 failed in Maths & Chemistry. Find the number of people who failed in (assuming that none is passed in all subjects). We have the following equations: a+b+c+d+e+f+g=1000 a+b+d+e=658, b+d=166 b+d+c+f=372 d+e=434 as in the figure. d+e++g=590, d+f=126. Find the values. Physics but neither Chemistry nor Maths.

In a class , 40 student like Maths, 50 students like Physics and 60 students like Chemistry. 30 students like both Maths and Physics, 20 students like both Physics and Chemistry and none of them like both Maths of Chemistry . Find the total number of students who like only Maths, only Physics and only Chemistry.

12th Chemistry महत्वपूर्ण प्रश्नों का महा-संग्राम | 12th Chemistry Most Important Objective Question

In a school, students must take at least one of these subjects: Maths, Physics or Chemistry. In a group of 50 students, 7 take all three subjects. 9 take Physics and Chemistry only, 8 take Maths and Physics only and 5 take Maths and Chemistry only. Of these 50 students, x take Maths only, x take Physics only and x + 3 take Chemistry only. Draw Venn diagram, find x, and hence find the number taking Maths.

For an examination consisting of three subjects -Maths Physics and Chemistry, 280 students appeared. When the results were declared, 185 students had passed in Maths, 210 had passed in Physics and 222 had passed in Chemistry. All those except 5 students who passed in Maths, passed in Physics. All those except 10 students who passed in Maths, passed in Chemistry. 47 students failed in all the three subjects. 200 students who passed in Physics also passed in Chemistry : How many students passed in Maths but failed in both Physics and Chemistry ?

In a boards examination,40 students failed in physics,40 in chemistry and 35 in mathematics,20 failed in maths and physics,17 in physics and chemistry,15 in maths and chemistry and 5 in all the three subjects.If 350 students appeared in the examination, how many of them did not fail in any subject?
