a) 20% b) 80% c) 70% d) 50%

**Ans**: d

**Solution**: Suppose the CP of each article is 1

Then CP of 10 articles = 10

SP of 10 articles = 15

Profit = 5

% profit = 5/10 × 100 = 50%

**2. The cost price of 36 books is equal to the selling price of 30 books. The gain per cent is?**

a) 15% b) 82 2/6% c) 20% d) 16 4/6%

**Ans**: c

**Solution**: Required profit

(36 – 30)/30 × 100= 20%

**3. The selling price of 5 articles is the same as the cost price of 3 articles. The gain or loss percent is?**

a) 40% gain b) 40% loss c) 20% loss d) 20% gain

**Ans**: b

**Solution**:

Let CP be 1

C.P. of 3 articles = 3

= SP of P of 5 articles

Loss% = (5 – 3)/5 × 100

= 2 × 20 = 40%

**4. The cost price of 18 articles is equal to the selling price of 15 articles. The gain per cent is?**

a) 10% b) 30% c) 20% d ) 40%

**Ans**: c

**Solution**:

Gain % = (18 – 15)/15 × 100

**5. If the cost price of 15 tables be equal to the selling price of 20 tables, the loss per cent is:**

a) 10% b) 25% c) 45% d) 60%

**Ans**: b

**Solution** :

Let the cost price of one table = x

Cost price of 15 tables = 15x

and cost price of 20 tables = 20x

According to the question

Selling price of 20 tables = cost price of 15 tables = 15x

Loss = 20x – 15x = 5x

Loss% 5x/20x × 100%

= 25%

**6. A person sells 400 mangoes at the cost price of 320 mangoes. His percentage of loss is?**

a) 20% b)25% c) 30% d) 35%

**Ans**: a

Loss per cent 400 – 320/400 × 100

80/400 × 100 = 20%

a) 14.35% b) 20% c) 21.43% d) 16 2/3%

**Ans**: b

**Solution**:

Let CP of each orange be 1

Then, CP of 10 oranges = 10

SP of 10 oranges = 12

Gain % = (2/10 × 100)% = 20%

**8. If the cost price of 50 oranges is equal to the selling price of 40 oranges, then the profit per cent is**

a) 25% b) 50% c) 75% d) 100%

CP of 40 oranges = 40

and SP of 40 oranges = 50

Profit = (50 – 40) = 10

Profit % = 10/40 × 100 = 25%

**9. If the cost price of 10 articles is equal to the selling price of 9 articles, the gain or loss per cent is**
