SSC Selection Post 2023 PYQ — Question 57

The correct answer is option 3 i.e. Rs.1,600.

Let the cost be ₹x

The manufacturer gains 10%:

Selling price = x × $110\over100$ = $11x\over10$

Wholesale dealer gains 15%:

Selling price = $11x\over10$ × $115\over100$ = $253\over200$x

Retailer gains 25%:

Selling price = $253x\over200$ × $125\over100$ = $253x\over160$

⇒ $253x\over160$ = 2530

⇒ x = 1600
