Question

I know thoda long hai but please answer​

Answer 1

Answer:

Let ratio between shirt material and trouser material be 3x : 2x

The cost of shirt material = 50 × 3x = 150x

The selling price at 12% gain :

$\frac{100 + P\%}{100} \times CP \\ \frac{100 + 12}{100} \times 150x \\ \frac{112}{100} \times 150x = 168x$

The cost of trouser material : 90 × 2x = 180x

The selling price at 12% gain :

$\frac{100 +P\%}{100} \times CP \\ \\ \frac{100 + 10}{100} \times 180x \\ \\ \frac{110}{100} \times 180x = 198x$

According to the question,

168x + 198x = 36,600

366x = 36600

$x = \frac{36600}{366} = 100 \: meters$

Now, trouser material : = 2x

= 2 × 100

= 200 m

Hence, Hasan bought 200 meters of the trouser material.

Answer 2

Answer:

Let ratio between shirt material and trouser material be 3x : 2x

The cost of shirt material = 50 × 3x = 150x

The selling price at 12% gain :

\begin{gathered} \frac{100 + P\%}{100} \times CP \\ \frac{100 + 12}{100} \times 150x \\ \frac{112}{100} \times 150x = 168x \\ \end{gathered}

×150x=168x

The cost of trouser material : 90 × 2x = 180x

The selling price at 12% gain :

\begin{gathered} \frac{100 +P\%}{100} \times CP \\ \\ \frac{100 + 10}{100} \times 180x \\ \\ \frac{110}{100} \times 180x = 198x \\ \end{gathered}

×180x=198x

According to the question,

168x + 198x = 36,600

366x = 36600

x = \frac{36600}{366} = 100 \: metersx=

=100meters

Now, trouser material : = 2x

= 2 × 100

= 200 m

Hence, Hasan bought 200 meters of the trouser material.
