The Table given below presents the number of books on different subjects kept on separate shelves. Subjects with odd and even numbers are of Arts and Science respectively.
| Subjects | Number of books |
| S1 | 26 |
| S2 | 29 |
| S3 | 31 |
| S4 | 34 |
| S5 | 36 |
| S6 | 38 |
| S7 | 44 |
What is the ratio of the number of books of S1 and the average number of books per subject?
Answer & explanation
Correct answer: option 1
Average number of books = \(\frac{26 + 29 + 31 + 34 + 36 + 38 + 44}{7}\)
= \(\frac{ 238}{7}\)
= 34
Now , Number of books of S1 : Average number of Books per subject
26 : 34
13 : 17
