Question

express the situation the cost of 2kg apples and 3kg oranges is Rs.160 as linear equation in two variables​

Answer 1

Let the cost of apples per kg be ₹x

Let the cost of oranges per kg be ₹y

Total cost given= ₹160

Therefore the equation is

2x+3y=160

Answer 2

$Let \: cost \: of \: 1 \:kg \: Apples = Rs \: x$

$Cost \:of \:2\:kg \: Apples = Rs \:2x$

$Let \: cost \: of \: 1 \:kg \: Oranges = Rs \: y$

$Cost \:of \:3\:kg \: Oranges = Rs \:3y$

/* According to the problem given */

$Cost \: of \:2\:kg \:Apples \: and \: 3\:kg \\Oranges \: is \: Rs \: 160$

$\implies 2x + 3y = 160$

Therefore.,

$\red { Required \: Linear \: Equation : }$

$\green { \: 2x + 3y = 160 }$
