One third of a bamboo pole is burried in mud ,one sixth of it is in water and the part above the water is greater than or equal to 3 metre. Find the length of shortest pole.
Let length of the bamboo pole = Y m
Part buried in mud = Y / 3 m
Part in water = Y / 6 m
Total part buried in mud and water = Y /3 + Y/6 = 3Y / 6 = Y /2 m
As given in the question total length of the pole=
Y /2 + 3 = Y
Since Y / 2 = 3
So 3+ 3 = Y
Ans: 6 m.
