    91 l
    None of these
    Option A
    50 [1 – (10/50)]3 =128/5 l

     

  7. A 144 l of mixture contains HCL and H2SO4 in the ratio 5 : 7. How much HCL need to be added to this mixture so that the new ratio is 23 : 21 respectively?
    32 l
    25 l
    27 l
    29 l
    None of these
    Option A
    =144 =5:7
    =60 : 84
    Now == 21 = 84

    30 l
    25 l
    18 l
    15 l
    None of these
    Option C
    p+q =30 l
    (p-10*p/p+q)/ (q-10*q/(p+q) + 10) = 2/3
    2p-4/3q = 20
    p =18 l
