Correct Answer - Option 1 : Rs. 600
Given:
A cycle seller gives 10% discount on marked retail and still earns 26% profit.
The marked retail price of the cycle is Rs. 840.
Concept used:
Selling price = Marked price × (100 - discount%)/100
Selling price = cost price × ( 100 - profit%)/100)
Calculations:
Marked price. = 840
Selling price = 840 × (100-10)/100
⇒ 756
Now we know that we get a profit of 26% by selling this article, so
Cost price (100 + 26)/100) = 756
⇒ Cost price (126/100) = 756
⇒ Cost price = 600
∴ The correct choice will be option 1.
