Let the four consecutive natural numbers which are multiples of five be x - 5, x, x+5, x+10 respectively.
According to given condition,
(x-5) (x) (x+5) (x+10) = 15000
x (x+5) (x-5) (x+10) = 15000
(xsquare + 5x) (xsquare +10x - 5x - 50) = 15000
(xsquare +5x) (xsquare + 5x - 50) = 15000
Put xsquare + 5x =m
m(m - 50) = 15000
msquare - 50m = 15000
now solve this equation by middle term splitting method
