Ans. Let First Number = 5x [because it is multiple of 5.]
then Next Number = 5x + 5
According to ques.
5x ( 5x + 5 ) = 300
=> 25x2 + 25x = 300
=> 25x2 + 25x - 300 = 0
divide equation by 25, we get
=> x2 + x - 12 = 0
=> x2 + 4x - 3x - 12 = 0
=> x( x+4) - 3(x+4) = 0
=> (x+4) (x-3) = 0
Either (x + 4 ) = 0 or (x-3) = 0
=> x = -4 or x = 3
So, Multiple of 5 are : 15, 20
