A traders sells two acrticles, one at a loss of 10% and another at a profit of 15% but finally there is no loss or gain. If the total sale price of these two articles is Rs. 30,000, find the difference between their cost prices:

A. Rs. 5000

B. Rs. 6000

C. Rs. 7500

D. Rs. 8500

Answer: Option B

Solution(By Examveda Team)

10% of x = 15 % of y, where x + y = 30000
$$\frac{{\text{x}}}{{\text{y}}} = \frac{{3{\text{k}}}}{{2{\text{k}}}}$$
Hence, difference = k = Rs. 6000

    10/100*x=15/100*y
    Ratio is 2x:3y and x:y is 3:2
    The total so x+y=30000
    also x:y=3k:2k
    x+y means 3k+2k=5k
    So 5k=30000
    k=6000

    10% of x = 15% of y
    x/y=3/2.
    x+y=30000.
    x=18000,y=12000.
    x=0.9Cp1.
    y=1.15Cp2.
    Cp1=19800.
    Cp2=10200.
    Diff. Cp1-Cp2=9600.

    Try to solve it with ratios P:L = 3:2, 30000 = 18000 : 12000 (3:2), Difference = 6000

    From the question
    10 % x = 15% of y ...(i)
    x+y = 30000 ...(ii)

    from eq. (i)
    x / y = 3/2 ...(iii)

    by solving eq. (ii) & (iii) 
    x = 18000, y = 12000

    Hence, the difference =6000
