Question

Hasan buys two kinds of cloth materials for school uniforms, shirt material that

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 metres of the trouser material. He sells the

materials at 12% and 10% profit, respectively. His total sale is ₹36,600. How much

trouser material did he buy?​

Answer 1

Step-by-step explanation:

Let 2x m of trouser material and 3x m of shirt material be bought by him

Selling price of shirt material per meter = ₹ 50 + 50 ×(12/100) = ₹ 56

Selling price of trouser material per meter = ₹ 90 + 90 × (10/100) = ₹ 99

Total amount of sale = ₹36,600

According to the question,

(2x × 99) + (3x × 56) = 36600

⇒ 198x + 168x = 36600

⇒ 366x = 36600

⇒ x = 36600/366

⇒ x = 100

Total trouser material he bought = 2x = 2 × 100 = 200 m.
