Question

A beaker has 1 litre of water. Raju draws water from the beaker in several steps that
follow a certain pattern. To begin with, he draws one-half of the water in the beaker.
He then draws one-third of the remaining water in the beaker. Finally, he draws one-
fourth of the remaining water in the beaker. How much water did Raju remove from
the beaker in these three steps?

Answer 1

Answer:

$\frac{3}{4}$

PLS MARK AS BRAINLIEST.

Step-by-step explanation:

STEP-1

He removes

$\frac{1}{2}$

of the water from the beaker.

Amount of water remaining in beaker

$= \frac{1}{2}$

STEP-2

Then he removed

$\frac{1}{3}$

from the remaining water.

.: He removed

$\frac{1}{3} \: of \: \frac{1}{2} \\ = \frac{1}{3} \times \frac{1}{2} \\ = \frac{1}{6}$

Amount of water remaining in beaker

$= \frac{2}{3} \: of \: \frac{1}{2} \\ = \frac{2}{3} \times \frac{1}{2} \\ = \frac{1}{3}$

STEP-3

Then he removed

$\frac{1}{4}$

from the remaing water

.: He removed

$\frac{1}{4} \: of \: \frac{1}{3} \\ = \frac{1}{4} \: \times \: \frac{1}{3} \\ = \frac{1}{12}$

Total water he removed,

$= \frac{1}{2} + \frac{1}{6} + \frac{1}{12} \\ = \frac{6 +2 + 1 }{12} \\ = \frac{9}{12} \\ = \frac{3}{4}$

Answer 2

Answer:

$\huge\mathbb\fcolorbox{purple}{lavenderblush}{✰Answer}$

Step-1

He removes $\tt \: \frac{1}{2}$of the water from the beaker .

Amount of water remaining in beaker$\tt = \frac{1}{2}$

Step-2

Then he removed $\tt \frac{1}{3}$from the remaining water.

ஃ He removed $\tt \frac{1}{3} \: of \: \frac{1}{2} = \frac{1}{3} \times \frac{1}{2} = \frac{1}{6}$

Amount of water remaining in beaker$\tt= \frac{2}{3} of \: \frac{1}{2} = \frac{2}{3} \times \frac{1}{2} = \frac{1}{3}$

Step-3

Then he removed $\tt \: \frac{1}{4}$

From the remaining water

ஃ‍He removed $\tt\frac{1}{4} of \: \frac{1}{3} = \frac{1}{4} \times \frac{1}{3} = \frac{1}{12}$

total water he removed,

$\tt= \frac{1}{2} + \frac{1}{6} + \frac{1}{12} \\ \\ = \tt\frac{6 + 2 + 1}{12} \\ \\ \tt = \frac{9}{12} = \frac{3}{4}$
