Question

Hasan buys two kinds of cloth materials for school uniforms, shirt material that costs him ₹ 50 per metre and trousers material that costs him ₹ 90 per metre. For every 3 metres 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 ₹ 36,660. How much trouser material did he buy?​

Answer 1

• 200.33 m

Explanation:

Let the amount of shirt material is s and trouser material is t.

We have equations based on given details:

• s/t = 3/2
• s*50*(1 + 0.12) + t*90*(1 + 0.1) = 36660

Simplify and solve for t by substitution:

• s = 3/2t
• 56s + 99t = 36660

• 56*3/2t + 99t = 36660
• 84t + 99t = 36660
• 183t = 36660
• t = 36660/183
• t = 200.33 m
