Answer:

Let 'x' be the cost price.

Now Marked price

$= x + \frac{30x}{100}$

$= \frac{13x}{10}$

$10$% discount

$= \frac{10}{100} \times \frac{13x}{10}$

$= \frac{13x}{100}$

Selling price

$= \frac{13x}{10} - \frac{13x}{100}$

$= \frac{117x}{100}$

Given gain =$340$

Here gain,

$= \frac{117x}{100} - x$

$= \frac{17x}{100}$

$= 340$

x = Rs. $2000$

Therefore,

Correct option A) 2000

Heyy mate ❤✌✌❤

Here's your Answer...

Let 'x' be the cost price.

Now Marked price = x + 30x/100 = 13x/10

10% discount = 10/100 x 13x/10 = 13x/100 

Selling price = 13x/10 - 13x/100 = 117x/100

Given gain = 340

Here gain = 117x/100 - x = 17x/100 = 340

=> x = Rs. 2000.
