Question

If you sell an item for Rs 69, you get 15% profit. If you sell that item for Rs 72, what is the profit?​

Answer 1

Step-by-step explanation:

Let CP be Rs. x.

According to the question,

(78−x)=2(69−x)

78−x=138−2x

⇒x=138−78=60.

Hence, CP=Rs

. 60.

Answer 2

Answer:

$cp \: = \frac{100}{100 + 15} \times 69$

$= 60$

$gain \: = 72 - 60 = 12$

$gain \% = \frac{12}{60} \times 100 = 20\%$
