Answer 1

Answer:

$\large{\underline{ \underline {\bf \pmb{Given}}}}$

• ➟ Cost of 15 eggs is Rs.75

$\large{\underline {\underline{ \bf \pmb{To \: Find} }}}$

• ➟ Cost of 4 dozens eggs.

$\large{\underline {\underline {\bf \pmb{Solution}}}}$

${ \bigstar \: \underline \frak \red{ \pmb{Firstly \: converting \: 4 \: dozens \: eggs \: into \: number \: of \: eggs }}}$

As we know that

$\implies \sf {1 \: dozens = 12}$

So,

$\implies \sf {4 \: dozens = 12 \times 4}$

$\implies \sf {4 \: dozens = 48}$

$\bigstar \underline \frak \red {\pmb{According \: to \: the \: question}}$

$\because \sf \: Cost \: of \: 15 \: eggs = Rs.75$

$\because \sf \: Cost \: of \: 1\: egg= \dfrac{75}{15}$

$\because \sf \: Cost \: of \: 1\: egg= \cancel\dfrac{75}{15}$

$\therefore \bf \purple{Cost \: of \: 1\: egg= Rs.5}$

$\because \sf \: Cost \: of \: 1 \: egg= Rs.5$

$\because \sf \: Cost \: of \: 48\: egg= 5 \times 48$

$\therefore \bf \purple{ Cost \: of \: 48\: egg= 240}$

$\begin{gathered}\: \: \end{gathered}$

$\large\underline {\star \: \frak \red{ \pmb{Henceforth,The \: cost \: of \: 4 \: dozens \: (48) \: eggs \: is \: Rs.240.}}}$
