Answer 2

${\bf{Given\::}}$

• Cost of 15 eggs is Rs.75.

$\\ {\bf{To\: Find\::}}$

• The cost of 4 dozens eggs.

$\\ {\bf{Solution\::}}$

As we know that,

$\orange\bigstar\:{\Large\mid}\:\bf\purple{1\:dozen\:=\:12\:}\:{\Large\mid}\:\green\bigstar$

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

$:\implies\:\bf{4\: dozens\:eggs\:=\:48\:eegs}$

Given that,

$\dashrightarrow\:\tt{15\:eggs\:costs\:=\:Rs.75\:}$

$\dashrightarrow\:\tt{1\:eggs\:costs\:=\:\dfrac{75}{15}\:}$

$\dashrightarrow\:\tt{1\:eggs\:costs\:=\:Rs.5\:}$

$\dashrightarrow\:\tt{48\:eggs\:costs\:=\:5\times{48}\:}$

$\dashrightarrow\:\bf\pink{48\:eggs\:costs\:=\:Rs.240\:}$

∴ ⑷ The cost of 4 dozens eggs is Rs.240.
