Given:

एक बास का 1/4 भाग कीचड़ में तथा 1/3भाग पानी में और 10 फीट पानी के ऊपर है

To find:

तो बास की लंबाई ज्ञात करें

Solution:

Let "x" ft represents the height of the pole.

So,

The length of the part of the pole inside the mud = \frac{x}{4} \:ft

The length of the part of the pole in the water = \frac{x}{3} \:ft

The length of the part of the pole above the water = 10 ft

Therefore, we can form the equation as:

\frac{x}{4} + \frac{x}{3} + 10 = x

\implies \frac{3x\: +\: 4x \:+\: 120}{12}  = x

\implies3x\: +\: 4x \:+\: 120  = 12x

\implies 7x \:+\: 120  = 12x

\implies 12x - 7x =   120

\implies 5x  =   120

\implies \bold{x = 24\:ft}

Thus, the length of the pole is → 24 ft.

A certain height of the pole is fixed in a lake whose one third is in mud, one-fourth of the remaining in sand and half of the remaining in the water. If the rest 6 m is seen above water, find the total length of the pole.
