  • math - ,

    Tap a filled for 8 mins=8x6=48 lit.
    Tap b drained for 6 mins=6x2=12 lit.
    Water remaining=48-12=36 lit=36000ml
    Ht of water in tank=36000/(50x40)=36/2=18 cm

  • math - ,

    A full tank will hold 56 L
    Using the calculations of anonymous of 36 L of water after both taps are turned of,

    h/28 = 36/56
    h = 28(36/56) = 18

    the water is 18 cm deep
