    400
    500
    600
    700
    Option A
    Let CP= Rs.x
    profit = 2 loss
    ie) 1000- x= 2( x-800)
    =>3x=1800
    =>x= CP= Rs.300

     

  2. A vendor purchased 50 kg of tomatoes from Farm 1 at Rs. 20 per kg and 30 kg of tomatoes for Rs. 22 per kg. He mixed two farms tomatoes for sale..At what rate the vendor should be sold to get 10% profit?

    34
    22
    23
    Option E
    CP of two farms tomatoes= Rs.( 50 *20 + 30 *22)
    = Rs. 1660
    CP of 1 kg tomatoes= 1660/(50+30) =1660/80 = Rs.20.75
    Profit % = 10%
    =>SP of 1 kg tomatoes= 20.75 * 110/100
    = Rs.23 ( approx)

    4800
    Option B
    Let the marked price be Rs.x
    S.P = x*90/100 * 108/100 = Rs.4860
    => x= 4860*100 *100/ 90*108
    => x= Rs.5000
