.Ramu & sangeetha went for biological analysis to a island which is 34km from their place. They travelled in a boat which went at a speed of 2m/s. when they are in half a distance in the boat sangeetha note there are 7 leg & 8 leg octopuses under the water. Ramu counted the total number of legs of octopuses and got 54. Sangeetha instantly said I know how many 7 leged octopuses are there under the water. They both reached the island after 20 min they left . How many seven leged octopuses does sangeetha calculate?

```										Dear student,
Total number of legs of both 7 & 8 leged octobus = 54. Find number of 7 leged octopuses Go from answer 4(7 leged octobus) + X = 54. 5(7 leged octobus) + X = 54. Similarly do for all. The x you get should  be exactly divisible by 8. Only one answer will satisfy the condition.

All the best.

I am not sure the question is correct. The series do not have any pattern if the third term of series is 35/7 instead of 37/5, it can be summed easily. Please confirm.
