1.	of 100 students, 80 passed in Science, 71 passed in Math, 10 failed in both subjects nd 7 did not appear in an examination. Find the number Out of students who passed in both subjects by representing the above information in a Venn-diagram.
Answer» Answer: 68 is the correct answer Step-by-step explanation: Out of 100, 10 failed and 7 didn't appear in the exam. This means 100— 10— 7=83 PASSED altogether. Now passed 80(SCIENCE)+71(Maths)=151 And 151-83=68 passed in Science and Maths both. The NUMBER 68 is being COUNTED in both 80 and 71. Hence 80— 68=12 passed in Science only. 71— 68=3 passed in Maths only Whereas 68 passed in both

Answer:

68 is the correct answer

Step-by-step explanation:

Out of 100, 10 failed and 7 didn't appear in the exam. This means 100— 10— 7=83 PASSED altogether.

Now passed 80(SCIENCE)+71(Maths)=151

And 151-83=68 passed in Science and Maths both.

The NUMBER 68 is being COUNTED in both 80 and 71. Hence

80— 68=12 passed in Science only.

71— 68=3 passed in Maths only

Whereas 68 passed in both
