  1. we dont know manish's height when he was 3 years old.

  2. nail didn't go any higher, it was the tree that grew not the nail!!!
    so the nail was at the same spot.

  3. it would be 30cm higher if it was a newly planted baby tree but if it wasn't then it would not have moved at all.

  4. Should be 30 but if it was just the leaves and branches at the top the made the 5cm each year the nail would not have moved.

  5. What is top in this case. If the nail is put 4 feet above ground and 6 inch below the so called top. What will be the position of nail ahter six years?
