    14(22/27)%
    Option E
    Total CP = 1.8 × 144 = Rs. 259.2
    Total SP = ( 100– 125/900)*144*2.4 = Rs.297.6
    Gain percentage = ( 297.6– 259.2)/259.6*100 = 14(22/27)%

    1.4====0.6
    Ratio = 7:3
    Required Quantity = 27/3*7 = 63 kg

    5 kmph
    1 kmph
    2 kmph
    4 kmph
    3 kmph
    Option B
    Let downstream speed = x
    Upstream speed = y 15/ 𝑥 = 3(45/60)
    =>15/𝑥 = 15 4
    =>𝑥 = 4
    5/ 𝑦 = 2(30/60)
    =>5/ 𝑦 = 5/ 2
    => 𝑦 = 2
    Speed of current = 1 kmph
