  1. The published answer (16 m) is incorrect in my view…
    If a 2 m pole casts a 3 m shadow, a 4 m pole will cast a 6 m shadow.
    Hence, if the wall weren’t there, the 4 m shadow currently on wall would have cast a further 6 m long shadow.
    Thus, the total length of the shadow of red pole would have been
    = 6 + 6 = 12 m.
    Hence, the height of red pole
    = (2×12)/3 = 8 m.

    • Use the 2:3 rule for the shadow too i.e. a 4m pole casts a 6m shadow, so an upright (90°) 8m shadow is in fact 12m parallel to the ground. It seems to be 8m cause it’s upright
