Question

Find the CP of an article which was sold for Rs 799/- at a gain of 9%.

Answer 1

Answer:

CP = Rs 733.03

Step-by-step explanation:

According to Question:

SP = 799

G% = 9%

CP = ?

Let CP be x

Using The Identity,

G% = $\frac{G}{CP}*100$

9 = ( G * 100)/x  

We Know that, Gain = SP - CP

G = 799 - x

Putting the value of G in the equation,

9 = ((799 - x )*100) / x

9x = 79900 - 100x          (Cross- Multiple)

9x + 100x = 79900

109x = 79900

x = 79900/109

x = 733.03

CP = Rs 733.03
