  6. A trader buys two goats for Rs 3000.He sells first goat at a profit of 22% and the second goat at a loss of 8%.What is the SP of second goat if in the whole transaction there is no profit no loss?
    Rs 2024
    Rs 3025
    Rs 2540
    Rs 2550
    None of these
    Option A
    CP of first goat=x
    CP of second goat=750-x
    SP of first goat=122x/100
    SP of second goat=92/100(750-x)
    3000=122x/100 + 92/100(3000-92/100x)
    x=800
    Therefore,CP of second goat=3000-800=2200
    SP=92/100*2200
    =Rs 2024

     

  7. Sum of CP’s of two goats is Rs 39000.Both the goats are sold at a profit of 20% and 40% respectively with their SP’s being the same.What is the difference of CPs of both the goats?
