How To Make Notes In Chemistry | Class 12 Boards | Boards Exam 2020 | Preparation Tips

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?

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 Chemistry only ?

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 or Maths but not in Chemistry.
