10) Difference between the cost price of two products is $10. Difference between the selling price is $20. If one is sold at 20% profit and other one is sold at 20% loss, find the cost price of each product.

**Answer (1) : **

Cost price (C.P) = $40

Selling price (S.P) = $75

Mark up value = 75 - 40 = $35

Mark up rate = (35 / 40) ⋅ 100% = 87.5%

So, the mark up rate is 87.5 %

**Answer (2) : **

Selling price (S.P) = (100 - m)% ⋅ L.P -----(1)

Here,

L.P = $55, m = 25

Substitute 55 for L.P and 25 for m in (1).

(1)-----> S.P = (100 - 25)% ⋅ 55

S.P = 75% ⋅ 55

S.P = 0.75 ⋅ 55

S.P = 41.25

So, the selling price is $ 41.25.

**Answer (3) : **

Selling price (S.P) = (100 - m)% ⋅ Original price -----(1)

Here,

S.P = 127.46, m = 15

Substitute 127.46 for S.P and 15 for m in (1).

127.46 = (100 - 15)% ⋅ Original price

127.46 = 85% ⋅ Original price

127.46 = 0.85 ⋅ Original price

127.46 / 0.85 = Original price

149.95 = Original price

So, the original price is $ 149.95.

**Answer (4) :**

Let x be the cost price of A.

Then, we have

Cost price of B = 1.15x

Cost price of C = 1.2(1.15x)

Cost price of C = 1.38x

**Given :** The cost of C is $1656.

1.38x = 1656

Divide each side by 1.38

x = 1200

So, the price at which A bought the item is $1200.

**Answer (5) :**

As per the question, we need 15% mark up rate on $1500.

Selling price for 15% on 1500 :

S.P = 115% ⋅ 1500

S.P = 1.15 ⋅ 1500

S.P = 1725

When all the good sold, we must have received $1725 for 15% mark up rate.

When we look at the above picture, in order to reach 15% mark up rate overall, the rest of the goods ($1200) has to be sold for $1470.

That is,

C.P = $1200

S.P = $1470

Profit = $270

Mark up rate = (270 / 1200) ⋅ 100%

Mark up rate = 22.5%

So, the rest of the goods to be sold at the mark up rate of 22.5% in order to have the mark up rate of 15% overall.

**Answer (6) :**

Let x be the S.P of 5 articles.

**Given :** Profit of 20 articles is S.P of 5 articles

Then, profit of 20 articles is x.

S.P of 20 articles = 4(S.P of 5 articles)

S.P of 20 articles = 4x

C.P of 20 art. = S.P of 20 art. - Profit of 20 art.

C.P of 20 articles = 4x - x

C.P of 20 articles = 3x

Mark up rate = (x / 3x) ⋅ 100%

Mark up rate = (1/3) ⋅ 100%

Mark up rate = 33.33%

**Answer (7) :**

Let the cost price be $100.

Then, the selling price is $120.

Let x be the marked price.

From the above picture, we get

80% of (M.P) = S.P

(0.8)x = 120

x = 150

Therefore, the marked price is $150.

Cost price = $100

Marked Price = $150

So, the required percentage increase is 50%.

**Answer (8) :**

Let the cost price of one article be $1 -----(1)

**Given : **The selling price of 10 articles is the cost price of 15 articles.

Then, we have

S.P of 10 articles = 15 ⋅ 1 = $15

S.P of one article = 15 / 10 = $1.5 -----(2)

From (1) and (2), the selling price is more than the cost price.

That is, S.P > C.P

So, there is profit.

Profit = (2) - (1)

Profit = 1.5 - 1

Profit = 0.5

Profit percentage = (0.5 / 1) ⋅ 100 = 50%

So, the profit percentage = 50%.

**Answer (9) :**

Let m be the cost price of one unit.

Then, we have

Cost price of 5 units = 5m

Cost price of 20 units = 20m

**Given :** On selling 20 units of an item, the profit is equal to cost price of 5 units.

Then, we have

Profit on selling 20 units = C.P of 5 units = 5m

Mark up rate = (profit / cost) ⋅ 100%

Mark up rate = (5m / 20m) ⋅ 100%

Mark up rate = (1 / 4) ⋅ 100%

Mark up rate = 25%

**Answer (10) :**

Let x and y be the cost prices of two products.

Then, we have

x - y = 10 -----(1)

Let us assume that x is sold at 20% profit.

Then, the selling price of x is

= 120% ⋅ x

= 1.2x

Let us assume that y is sold at 20% loss.

Then, the selling price of y is

= 80% ⋅ y

= 0.8y

**Given :** Difference between the selling price is $20

1.2x - 0.8y = 20

Multiply each side by 10.

12x - 8y = 200

Divide each side by 4.

3x - 2y = 50 -----(2)

Solving (1) and (2), we get

x = 30

y = 20

So, the cost prices of the two products are $30 and $20.
