Question

if i lose 9% by selling chocolate at the rate of 15 far a rupee,how many a rupee must i sell them so as to gain 5% ?​

Answer 1

Answer:

loss%=9/100=(cp-sp)/100

=cp/100-15/100

so

(9/100)+(15/100)=cp/100

so cp was 24

Step-by-step explanation:

Now to gain 5%

add 5% to 24

we get 24*1.05

=25.20 ANSWER

Answer 2

The selling price is Rs. 17.304.

Step-by-step explanation:

Since we have given that

Loss % = 9%

Selling price = Rs. 15

So, cost price would be

$\dfrac{100}{100-9}\times 15\\\\=\dfrac{100}{91}\times 15\\\\=16.48$

So, if gain% = 5%

Then, selling price would be

$\dfrac{100+5}{100}\times 16.48\\\\=\dfrac{105}{100}\times 16.48\\\\=1.05\times 16.48\\\\=17.304$

Hence, the selling price is Rs. 17.304.
