Question

A motor pumps out 6704.76 litres of water from a tank in 6 hours. How many litres of water will it pump out in one hour ?​

Answer 1

Given that:

• A motor pumps out 6704.76 litres of water from a tank in 6 hours.

To Find:

• How many litres of water will it pump out in one hour?

Let us assume:

• It out x litres of water from a tank in one hour.

Finding volume of water out from a tank in 1 hour:

According to the question.

Volume : Time = Volume : Time

↣ x : 1 = 6704.76 : 6

↣ x/1 = 6704.76/6

Cross multiplication.

↣ x = 1117.46

Hence,

• A motor pumps out 1117.46 litres of water from a tank in one hour.

Answer 2

Answer:

Given :-

• A motor pumps out 6704.76 litres of water from a tank in 6 hours.

To Find :-

• How many litres of water will it pump out in one hour.

Solution :-

Let,

$\mapsto$ The litres of water will it pump out in one hour be y litres.

$\pink{\bigstar}\: \: \: \bf{According\: to\: the\: question\: :-}$

$\longrightarrow \sf y : 1 =\: 6704.76 : 6$

$\longrightarrow \sf \dfrac{y}{1} =\: \dfrac{6704.76}{6}$

$\longrightarrow \sf \dfrac{y}{1} =\: \dfrac{\dfrac{670476}{100}}{6}$

$\longrightarrow \sf \dfrac{y}{1} =\: \dfrac{670476}{100} \times \dfrac{1}{6}$

$\longrightarrow \sf \dfrac{y}{1} =\: \dfrac{670476}{600}$

$\pink{\bigstar}\: \: \: \bf{By\: doing\: cross\: multiplication\: we\: get\: :-}$

$\longrightarrow \sf 600y =\: 1(670476)$

$\longrightarrow \sf 600y =\: 670476$

$\longrightarrow \sf y =\: \dfrac{670476}{600}$

$\longrightarrow \sf\bold{\red{y =\: 1117.46\: litres}}$

$\therefore$ The litres of water will it pump out in one hour is 1117.46 litres.
