Answer 2

............Hello Friend............

Here is your answer below,

$= > x + y = 10 \\ = > y = 10 - x .....(1)\\ \\ = > \frac{50}{100} x + \frac{25}{100} y = \frac{10 \times 40}{100} \\ = > \frac{50x + 25y}{100} = \frac{400}{100} \\ = > 50x + 25y = 400 \\ = > 25(2x + y) = 400 \\ = > 2x + y = 16 .........(2)\\ \\ now \: put \: the \: value \: of \: y \: in \: equation \: \: (2). \\ = > 2x + y = 16 \\ = > 2x + 10 - x = 16 \\ = > x = 16 - 10 \\ = > x = 6 \\ \\ now \: put \: the \: value \: of \: x \: in \: equation \: (1). \\ = > y = 10 - x \\ = > y = 10 - 6 \\ = > y = 4$

I hope that helps you,
