\huge\mathcal\pink{ANSWER:-}

Let C, M & S denote respectively the cost-price, the marked-price & the sell-price of the given article.

The \:  \:  given \:  problem \:  is \:  described \:  explicitly \:  as  \: shown  \:  \: below,

The previously marked price of the article is Rs. 4200. So we get, M = 4200 …… (1)

It was sold at a discount of 16.66%. So we get, S = (1 - 0.1666)*M = (1 - 1/6)*M = (5/6)*M = (5/6)*4200 [from (1)] or S = 3500 …… (2)

If there was a loss of 9.09%, then what was the cost price? So we get, S = (1 - 0.0909)*C = (1 - 1/11)*C = (10/11)*C or C = (11/10)*S= (11/10)*3500 [from (2)] or C = 3850 (Rs) [Ans]

METHOD 1:

we know that,

sp =  \frac{100 + profit\%}{100}  \times cp

sp =  \frac{100 + 15}{100}  \times 4200

sp =  \frac{115}{100}  \times 4200

sp =  \frac{115 \times 4200}{100}

sp = 4830

METHOD 2:

we know that,

 \frac{profit}{cp}  \times 100 = gain\%

Let profit be x

 \frac{x}{4200}  \times 100 = 15

 \frac{x \times 100}{4200}  = 15

 \frac{x}{42}  = 15

x = 15 × 42

x = 15 × 42 = ₹630

sp = 4200+630

sp = 4830

hope it helps

have a great day
