Answer 2

The cost price of article is Rs. 2000

Step-by-step explanation:

let the cost price of an article is x and the marked price be y

therefore

100 - 22 = 78%

i.e

78% of x = 60% of y

$\frac{39 x}{50}= \frac{3y }{5} \\\\x= \frac{10y}{13}$

again according to question

60% of 140% of y - x = 184

$\frac{21y}{25}-x = 184\\\\\frac{21y}{25}- \frac{10y}{13}= 184 \\\\\frac{273y-250y}{325}= 184\\\\23y = 184 \times 325 \\\\y = \frac{184 \times 325 }{23}\\\\y = 2600$

i.e The marked price of the article is Rs. 2600

now,

The cost price of the article is

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

y = 2600

thus ,

$x = \frac{10\times 2600}{13}$

x = Rs. 2000

hence ,The cost price of article is Rs. 2000
