Alex3 years ago
8 0

Step-by-step explanation:

Because 2x and 40° are complementary angles.

\therefore \: (2x) \degree + 40 \degree = 90 \degree \\  \\  \therefore \: (2x) \degree  = 90 \degree  - 40 \degree \\  \\ \therefore \: (2x) \degree  = 50 \degree  \\  \\ \therefore \: 2x  = 50  \\  \\  \therefore \: x  =  \frac{50}{2}  \\  \\ \huge \red{ \boxed{ \therefore \: x  = 25}}

Answer:

  ₹14000

Step-by-step explanation:

Let c represent the cost price, and m represent the marked price.

  c × (1 +40%) = m

  m × (1 -15%) - c = ₹1900

Using the first expression for m, the second equation becomes ...

  1.40c×0.85 -c = ₹1900

  0.19c = ₹1900

  c = ₹1900/0.19 = ₹10000

Then the marked price was ...

  m = 1.40c = 1.40×₹10000 = ₹14000

The marked price was ₹14000.

_____

The selling price was ₹11900.
