1. Find selling price in the following cases. a) Market price = Rs 480,discount = Rs 40
b) Market price = Rs 870, discount = Rs 75.
2. Find cost price or selling price in the following cases.
a) cost price = Rs 120, profit = Rs 25
b) selling price = Rs 200, profit = Rs 20

1) a. Rs 440.

1) b. Rs 795.

2) a.Rs 145.

2) b. Rs 180.

Step-by-step explanation:

1) a.

Given,

Marked Price = Rs 480

Discount Amount = Rs 40

Selling Price = ?

Now,

Selling Price = Marked Price - Discount Amount

= Rs 480 - Rs 40 = Rs 440.

1) b.

Given,

Marked Price = Rs 870

Discount Amount = Rs 75

Selling Price = ?

Now,

Selling Price = Marked Price - Discount Amount

= Rs 870 - Rs 75 = Rs 795.

2) a.

Given,

Cost Price = Rs 120

Profit = 25

Selling Price = ?

Now,

Selling Price = Cost Price + Profit

= Rs 120 + Rs 25 = Rs 145.

Given,

Selling Price = Rs 200

Profit = Rs 20

Cost Price = ?

Now,

Cost Price = Selling price - Profit

= Rs 200 - Rs 20 = Rs 180.
