  1. A trader sells two articles, 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 there cost price :
    1. Rs.5000
    2. Rs.6000
    3. Rs.7500
    4. none of these
  1. Correct Option: B

    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
