Question

A shopkeeper offers two successive discounts of 10% and 5% on a saree whose marked price is ₹4500. Find its selling price.

Answer 1

Equivalent Discount,
=(A + B) - (AB/100)
= (10 + 5) - (10*5/100)
= 14.5%.
Let SP = X.
Now,
X - 14.5% of X = 171(Selling Price)
0.855X = 171
X = 200.
Hence, SP = Rs. 200.

Going through options,
200(SP)==10%(disc.)==>180==5%(disc.)==>171(CP).

Answer 2

Given, the Marked price of the saree = 4500 and discount = 10% and 5%.

Selling price at 10% discount = 90/100 * 4500

                                                 = 4050.

Selling price at 5% discount on 4050  = 95/100 * 4050

                                                                = 3847.5

Selling price = 3847.5

Hope this helps!
