The following graph shows the area and production of S1 , S2 , S3 , S4 , S5 and S6.

Based on the information, the production ratio (production to land) is highest and lowest, respectively, in:

S2, S4

Lets solve one by one for each option

1. S2 , S1

Production ratio for S2 and S1 = \(\frac{856 }{765}\) = 1.11

2. S3, S6

Production ratio for S3 and S6 = \(\frac{729 }{864}\) = 0.84

3. S2, S4

Production ratio for S2 and S4 = \(\frac{856 }{964}\) = 0.88 

4. S2 , S3

Production ratio for S5 and S3 = \(\frac{856 }{729}\) = 1.17

So , Production ratio for S2 and S4 is lowest.

Ans :- S2, S4
