Ramu & sangeetha went for biological analysis to a island which is...
Given Information:
Ramu and Sangeetha traveled to an island 34km away at a speed of 2m/s in a boat. There are 7 leg and 8 leg octopuses under the water, totaling 54 legs counted by Ramu.

Calculation:
- Total number of octopuses = Total number of legs / Number of legs per octopus
- Total number of octopuses = 54 / (7 + 8) = 54 / 15 = 3.6

Explanation:
Since the total number of octopuses cannot be a decimal value, the number of octopuses must be a whole number. Thus, there are 3 seven-legged octopuses and 4 eight-legged octopuses to make a total of 54 legs.

Sangeetha's Calculation:
- Sangeetha can instantly know the number of 7-legged octopuses, as there are 3 seven-legged octopuses mentioned earlier.

Conclusion:
Therefore, Sangeetha can calculate that there are 3 seven-legged octopuses under the water.
