A result of a survey of 1000 persons with respect to their knowledge of Hindi (H), English (E) and Sanskrit (S) is given below:
What is the ratio of those who know all the three languages to those who do not know Sanskrit?
- A1/9
- B1/10
- C10/17
- D5/27
Solution & Step-by-step Explanation

1. Number of persons who know all the three languages: Given directly as 100.
2. Number of persons who do not know Sanskrit: This equals the sum of the groups completely outside the Sanskrit circle.
Now, we compute the ratio:
1. Number of persons who know all the three languages: Given directly as 100.
2. Number of persons who do not know Sanskrit: This equals the sum of the groups completely outside the Sanskrit circle.
Now, we compute the ratio:
