The product of two successive integral multiples of 5 is 300 . Determine the multiples. |
|
Answer» Let one number be x, so that the other number is x+5.According to the given question,x(x+5)=300x2+5x-300=0(x+20)(x-15)=300x=-20 and x=15 x cannot be negative, since the numbers are successive integral multiples of 5.So, x=15, and x+5=20Hence, the multiples are 15 and 20. Required numbers = 15 and 20 |
