 |
| What is the ratio of those who know all the three languages to those who do not know Sanskrit? |
A) \[\frac{1}{9}\]
B) \[\frac{1}{10}\]
C) \[\frac{10}{17}\]
D) \[\frac{5}{27}\]
Correct Answer: D
Solution :
The persons who know all the three languages are represented by the region which is common to all the three circles. So, number of such persons = 100 The persons who do' not know Sanskrit are represented by the region outside circle S. So, number of such persons = (200 + 120 + 220) = 540. \[\therefore \] Required Ratio \[=100:540=5:27\]
