• A

18.2%  • B

25%  • C

29.6%  • D

Cannot be determined  • Option : C
• Explanation :

Let CP be  x
∴ MP = 1.8 x
∴ SP of 15 articles = 12 * 1.8x = 21.6x
∴ Discount = 0.9 x 21.6x = 19.44x
∴Profit on 15 articles = (19.44 - 15)x
∴ Profit % =(4.44x/15x)  = 29.6%

• A

Rs.4000  • B

Rs.2000  • C

Rs.300  • D

Rs.2500  • Option : B
• Explanation :

Rate in which the rent is to be divided = 4 : 8 : 12
A's  share of rent= (8/24)  * 6000 =Rs.2000

• A

Rs.1000  • B

Rs.2000  • C

Rs.1500  • D

Rs.3000  • Option : A
• Explanation :

85% of the total profit is divided in the ratio 2 : 10 : 5.
85% of total profit = 2x + 10x + 5x = 17x
Total profit = (17x / 85% )
Share of Ram in the profit = 2x + 15% of 20x =2x+ 3x= 5x
Share of Shyam in the profit = 10x
Share of Ghanshyam in the profit = 5x
Now, (10x + 5x) - 5x = 500
10x = 500
=>x = 50
∴ Total profit = 20 x 50 = Rs.1000.

• A

Rs.5620  • B

Rs.4512  • C

Rs.3212  • D

None of these  • Option : B
• Explanation :

C.P. of goods for the trader = Rs.22520
S.P. = 125 x 22520 = Rs.28150
∴ Profit =  Rs.5630
Now, 5630 = 0.0536 x 5000 + 0.085 x 10000 + (x/100)* 7520
=>5630 =268 - 850 + 75.2x
=>75.2x = Rs.4512, which is nothing but profit from sale of third lot.

• A

The person is selling at a loss  • B

The person is selling at a profit.  • C

The loss or gain depends on the profit from sale of two articles.  • D

The person is selling at the cost price  • Option : C
• Explanation : Profit or loss of the sale depends upon how much profit the person is earning on the sale of two articles. If SP > CP of 1 article, there is a profit. If SP < CP of 1 article, there is a loss. If SP = CP of 1 article, there is not profit no loss. Thus, only (c) is true.
