Question

the ratio of the sale of eggs on a Sunday to the whole week of a grocery shop was 2 : 9 . if the total sale of eggs in the same week was Rs 360 , find the sale of eggs on Sunday.​

Answer 1

Answer:

The sale of eggs on Sunday = ₹80

Step-by-step explanation:

Given :

Ratio of sale of Sunday to sale in a week = 2:9

Sale in the week = ₹360

To find :

Sale of eggs in Sunday

Taken :

To find the sale of eggs on Sunday use this formula -:

$\boxed{\sf{S_{S}=\dfrac{R_{S}}{R_{W}}\:\times\:S_{W}}}$

Where,

$\sf{S_{S}}$ = Sale on Sunday

$\sf{S_{W}}$ = Sale in a week

$\sf{R_{S}}$ = Ratio of sale on Sunday

$\sf{R_{W}}$ = Ratio of sale in a week

Solution :

$:\implies\sf{S_{S}=\dfrac{2}{\cancel{9}}\:\times\:Rs.\cancel{360}}$

$:\implies\sf{S_{S}=2\:\times\:Rs.40}$

$:\implies\sf{S_{S}=Rs.80}$

So , the sale on Sunday is ₹80 .

Answer 2

AnsweR :-

$\large\sf \frac{Sale \: Of \: Sunday}{Sale \:Of \: Whole \: Week } = \frac{2}{9}$

$\large\sf{Sale \: of \: whole \: week = Rs.360}$

$\large \sf{Sale \: on \: Sunday = Rs.x}$

$\large \sf \frac{2}{9} = \frac{x}{360} \: [Cross \: Multiply]$

$\large\sf{⇒2×360=9×x}$

$\large\sf{⇒ x = \frac{2 \: × \: 360}{9 \: × \: x} }$

$\large\sf ⇒ 2×40$

$\large\sf ⇒ x=2×40=\color{red}\boxed{80}$

Therefore,

The sale on that Sunday =$\bf\color{blue}{₹80}$
