lesantik [10]

Answer:

Market Price = MP

Cost Price = CP

P1 = (MP - 10%) - CP = Rs8

- CP = Rs8 - 0.90% MP

CP = 0.90 MP - Rs8

P2 = MP - CP = Rs20

- CP = Rs20 -MP

CP = MP - Rs20

0.90 MP - Rs8 = MP - Rs20

- 0.10% MP = - Rs12

0.10% MP = Rs 12

MP = Rs120p

CP = MP - Rs20 = Rs120 - Rs20 = Rs100.

The cost price of the item is Rs100.

Please find the answer , it is a very importatnt question

Anna [14]

Step-by-step explanation:

The given expression is :

$\dfrac{2-\sqrt5}{2+3\sqrt5}=\sqrt5 x+y$ ....(1)

Taking LHS of the above expression

$\dfrac{2-\sqrt5}{2+3\sqrt5}$

Rationalizing both denominator and numerator.

$\dfrac{2-\sqrt5}{2+3\sqrt5}\times \dfrac{2-3\sqrt5}{2-3\sqrt5}=\dfrac{4-6\sqrt5-2\sqrt5+15}{2^2-(3\sqrt5)^2}\\\\=\dfrac{19-8\sqrt5}{4-45}\\\\=\dfrac{19-8\sqrt5}{-41}\\\\=\dfrac{\sqrt5 \times 8}{41}+(\dfrac{-19}{41})$

Equation (1) becomes,

$\dfrac{\sqrt5 \times 8}{41}+(\dfrac{-19}{41})=\sqrt 5\ x+y$

Equating both sides,

$x=\dfrac{8}{41}$ and $y=\dfrac{-19}{41}$

Hence, this is the required solution.
