$here \: is \: your \: answer$
Q. Hasan by two kinds of clothes material for school uniform shirt material that cost him rupees 50 per metre and trouser material that cost him rupees 90 per metre for everything of the shirt material he buys 2 metre of the trouser material he sell the material at 2% and 10% profit reprectively his total sale is rupees 36600 how much trouser did he buy?


Let's the shirt material purchased be = 3x m
trouser material 2x
$sp = \frac{cp \times profit}{100}$

$3x \times 50 = \frac{3x \times 50 \times 12}{100}$
$2x \times 90 = \frac{2x \times 90x10}{100} = 36600$

$150x + 18x + 180x + 18x = 36600$
$366x = 36600$
$x = \frac{36600}{366}$
$x = 100$
trouser material
$2x = 100 \times 2 = 200m$
