50 per metre and trouser material that costs him Rs 90 per metre. For every 2 meters 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 36660. How much trouser material did he buy?​

Answer 1

Answer:

Per metre trouser material cost = 90 Rs

3 metre trouser material cost = 90×3= 270Rs

Answer 2

Answer:

200 m

Step-by-step explanation:

1. Shirt = 3
2. Trouser = 2

1. Shirt = 3/2 * x
2. Trouser = 2/2 * x

Cost of shirt material = 50

Cost of trouser material = 90

Cost of shirt material for 3x/2 = 50 * 3x/2 = 75

Cost of trouser material for x = 90 * x = 90x

Profit of 10% (Trousers) = 10% of 90x = 10/100 * 90x = 9x

Profit of 10% (Trousers) = 12% of 75x = 12/100 * 75x = 9x

SP of trousers = 90x + 9x =99x

SP of trousers = 75x + 9x =84x

99x + 84x = 36600

183x = 36600

x = 36600/183 = 200 m
