Let C, M & S denote respectively the cost-price, the marked-price & the sell-price of the given article.
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 = ₹4830
METHOD 2:
we know that,
Let profit be ₹x
x = 15 × 42
x = 15 × 42 = ₹630
sp = ₹4200+₹630
sp = ₹4830
hope it helps
have a great day
