costs him 50 per metre and trouser material that costs him 90 per metre. For every 3 meters of the shirt material he buys 2 meters of the trouser material. He sells the material at 12% and 10% profit respectively. His total sale is rupees 36,600. How much trouser material did he buy​

Answer 1

Answer:

Let us assume that Hasan bought x meters of trouser material

so the shirt material Hasan bought is 3/2x = 1.5x

Cost of the trouser material is 90x and cost of shirt material is 50*1.5 x = 75x

He sells shirt material at a profit of 12%. So sales price is (12+100)*75x/100 = 84x

He sells trouser material for a profit of 10% so sales price is (10+100)*90x/100 = 99x

Now total sale is 36,600

99x + 84x = 36,600

183x = 36600

x = 200

He bought 200 m of trouser material
