Answer 2

Answer:

₹700

Step-by-step explanation:

Given,

A shopkeeper sells an article at a profit of 15%. Had he sold it for ₹21 more, he would have gained 18%.

To find,

The C.P. of the article

Procedure,

Important points =

• Profit = 15%
• Would be profit = 18% on selling at ₹21 more

Let the C.P. be x

$profit \: = 15\%$

$on \: selling \: the \: article \: at \:₹ 21 \: more \: gain = 18\%$

$18\% - 15\% = 3\%$

$3\% = ₹21$

$\therefore1\% = \frac{21}{3} \\ 1\% \: = ₹7$

$15 \% = ₹7 \times 15$

$15\% = ₹105$

$\therefore \: profit \: is \: ₹105$

$x = ₹\frac{100}{15} \times 105$

$x = ₹\frac{10500}{15}$

$x = ₹700$

Therefore, the C.P. of the article is ₹700.
