1. If cost of 15 eggs be 75 rupees, then find out the cost of 5 dozen eggs.
1. 300
2. 400
3. 500
4. 600

1. Cost of one egg x 5 x 12

##### Correct Option: A

Cost of 15 eggs = 75 rupees
Cost of 1 egg = 75/15 = 5 rupees,
Cost of 5 dozens, i.e. 5 x 12 = 60 x 5 = 300

1. A stationer buys diaries at 75 rupees per dozen and sells them at 15 rupees per piece. What is the profit?
1. 75
2. 100
3. 105
4. 110

1. Each dozen carries cost 75 rupees and are sold for
12 x 15 = 180 rupees

##### Correct Option: C

Each dozen carries cost 75 rupees and are sold for
12 x 15 = 180 rupees
profit = SP-CP
profit = 180-75 = 105 rupees

1. A man bought 18 oranges for a rupee and sold them at 12 oranges for a rupee. what is the profit percentage ?
1. 33.33 %
2. 50 %
3. 66.66 %
4. None of these

1. From question CP/SP = 12/18 = 2/3
∴ Profit (%) = ( 3 - 2 ) / 2 x 100

##### Correct Option: B

From question CP/SP = 12/18 = 2/3
∴ Profit (%) = ( 3 - 2 ) / 2 x 100 = 50%

2nd Solution:
CP = 100/18 = 5.55 paisa
SP = 100/12 = 8.33 paisa
∴ Profit = (8.33-5.55)/5.55 x 100 = 50 %

1. On selling an article for Rs. 240, a trader loses 4%. In order to gain 10 % he must sell that article for
1. Rs. 275
2. Rs. 340
3. Rs. 320
4. Rs. 264

1. Let the CP be Rs. x , then SP be 0.96x
∴ 0.96x = 240

##### Correct Option: A

Let the CP be Rs. x , then SP be 0.96x
∴ 0.96x = 240
⇒ x = 250

Now the new SP = 250 X 1.1 = 275

1. By selling 12 apples for a rupee, a man loses 20%. How many for a rupee should he sell to gain 20%
1. 8
2. 10
3. 15
4. 16

1. SP = 100/12 paise
Let's CP = x
SP = 0.8x = 100/12
∴ x = 10/(0.8x12) paise
Therefore, CP = 100/9.6 paise

##### Correct Option: A

SP = 100/12 paise
Let's CP = x
SP = 0.8x = 100/12
∴ x = 10/(0.8x12) paise
Therefore, CP = 100/9.6 paise

Thus the new SP (with 20% profit) = 100/9.6 X 1.2 = 100/8 paise
Hence, 8 apples can be purchased for Rs.1 to gain 20%
