The data given in the table shows the number of students studying in 4 different disciplines in 5 institutes. Study the table and answer the question:
| Institutes | Arts | Science | Commerce | Computer Science |
| A | 36 | 48 | 59 | 57 |
| B | 45 | 54 | 55 | 48 |
| C | 55 | 36 | 56 | 51 |
| D | 45 | 48 | 55 | 53 |
| E | 48 | 44 | 52 | 55 |
What is the ratio of the number of students studying Science in institutes C and D taken together to the number of students studying Computer Science in institutes A and E taken together?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 3 : 4.
The number of students studying Science in institutes C and D taken together = 36 + 48 = 84.
The number of students studying Computer Science in institutes A and E taken together = 57 + 55 = 112
Required ratio = 84 : 112 = 3 : 4.
