Question

7. Hasan buys two kinds of cloth materials for school uniforms, shirt material that
costs him 50 per metre and trouser material that costs him 3 90
per metre.
For every 3 meters of the shirt material he buys 2 meters of the trouser material. He sells the materials at 12% and 10% profit respectively. His total sale is 36,000. How much trouser material did he buy?

Answer 1

Answer:

200 meters

Step-by-step explanation:

Let the total cloth material for shirt = 3x m

Let the total cloth material for trousers = 2x m

Amount of total shirt material=3x×50=150 rupees

Amount of total trouser material=2x×90=180 rupees

______________________________________

S.P for shirt material= P% = 12%

S.P = (100 + 12/ 100) x C.P

S.P = (100 + 12/ 100) x 150x

S.P = 168x rupees

S.P for trouser material= P%= 10%

S.P = (100 + 10/ 100) x C.P

S.P = (100 + 10/ 100) x 180x

S.P = 198x rupees

______________________________________

So, 168x + 198x = 36600

366x = 36600

x = 100

So, the trouser material= 2x = 2 x 100 = 200 m
