Question

After allowing a discount of $10$% on the marked price, a trader sun makes a gain of $17$% what per cent is the marked price above the cost price?

Answer 1

Given that,

Discount $10$%

Gain $=17$%

Let the cost price=$100$ rupees

Selling price$=117$

Let marked price $x$.

Then,

$=\frac{90}{100}x=117$

$x=\frac{117\times 100}{90}$

$=130$

Then,

Cost price $=130-100=30$

We get marked price is $30$ rupees more than $CP$.
