Answer 2

$\mathfrak{\large{\underline{\underline{Answer :-}}}}$

The cost of $\tt\dfrac{2}{5}$ kg Almonds is Rs. 184.

$\mathfrak{\large{\underline{\underline{Explanation :-}}}}$

Given :

Cost of 1 kg Almonds = Rs. 460

To Find :

The Cost of $\tt\dfrac{2}{5}$ kg Almonds.

Solution :

$\textbf{Method I}$

By Proportion -

Consider the cost of $\tt\dfrac{2}{5}$ kg Almonds as x

1 : 460 : : $\tt\dfrac{2}{5}$ : x

Mean Terms = 460 and $\tt\dfrac{2}{5}$

Extreme Terms = 1 and x

$\boxed{\sf{Mean \times Mean\:Terms = Extreme \times Extreme \:Terms}}$

$\sf{\implies} \: 460 \times \dfrac{2}{5} = 1 \times x$

$\sf{\implies} \: 92 \times 2 = x$

$\sf{\implies} \: x = 184$

$\therefore$ The cost of $\tt\dfrac{2}{5}$ kg Almonds is Rs. 184.

$\rule{300}{1.5}$

$\textbf{Method II}$

By Unitary Method -

Cost of one Kg Almonds = Rs. 460

Cost of $\tt\dfrac{2}{5}$ kg Almonds is =

$\sf{\implies} \: \dfrac{2}{5} \times 460$

$\sf{\implies} \: 2 \times 92$

$\sf{\implies} \: 184$

$\therefore$ The cost of $\tt\dfrac{2}{5}$ kg Almonds is Rs. 184.
