Chemistry पढ़ने का आसान तरीका

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 ?

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

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.
