Question

an article was sold at a gain of 15% had it been sold for rupees 28 more the gain would have been 20% find the cost price of the article​

Answer 1

Answer:

Rs 2160

Step-by-step explanation :

Let say cost price = c

15% gain = (15/100) xc = 0.15c

20% gain = ( 20/100)xc = 0.2c

0.2c - 0.15c = 108

0.05c = 108

c = 108 / 0.05

c = 2160

Answer 2

Answer:

$\huge \mathfrak \red{Rs,2169}$

Since we have given that

Article was sold at a gain of 15% had it been sold for rupees 108 more the profit would have been 20%

Let the cost price be 'x'.

According to question, it becomes,

$\begin{gathered}\dfrac{20}{100}x-\dfrac{15}{100}x=108\\\\\dfrac{5}{100}x=108\\\\\dfrac{x}{20}=108\\\\x=20\times 108\\\\x=2160\end{gathered}$

• Hence, the cost price will be Rs.2160.
