Long Answer TypeHasan buys two kinds of cloth materials for school uniforms, shirt material that costs him Rs 50 per metre and trouser material that costs him Rs 90 per metre. For every 2 metres of the trouser material he buys 3 metres of the shirt material. He sells the materials at 12% and 10% profit respectively. His total sale is Rs 36,600. How much trouser material did he buy?
Let the length of cloth for trousers = 2x metres
∴ The length of cloth for shirts = 3x metres
Cost of trouser's cloth = 2x 
Rs 90
= Rs 180 x
Cost of shirt's cloth = 3x 
Rs 50
= Rs 150 x
S.P. of trouser's cloth at 10% profit = Rs ![<pre>uncaught exception: <b>mkdir(): Permission denied (errno: 2) in /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/com/wiris/util/sys/Store.class.php at line #56mkdir(): Permission denied</b><br /><br />in file: /home/config_admin/public/felixventures.in/public/application/css/plugins/tiny_mce_wiris/integration/lib/com/wiris/util/sys/Store.class.php line 56<br />#0 [internal function]: _hx_error_handler(2, 'mkdir(): Permis...', '/home/config_ad...', 56, Array)

= Rs 198 x
S.P. of shirt's cloth at 12% profit = Rs 
= Rs 168x
∴ Total S.P. = Rs 198x + Rs 168x
= Rs 366x
But the total S.P. = Rs 36600
∴ 366x = 36600
or 
[Dividing both sides by 366]
= 100
∴ 2x = 2 
100 = 200
Thus, he bought cloth for trousers = 200 metres.
