Answer:
116.4545454545455
Step-by-step explanation:
<span>10x + 30(2) = 20(x + 2)
10x + 60 = 20x + 40
10x = 20
answer
x = 2 liters
So you would need 2 liters of the 10% solution to make the 30% solution 20%.</span>
Let the numbers be X and X+1.
X+2(X+1)=29
X+2X+2=29
3X=29-2
X=27/3
X=9.
Thus, the Numbers are therefore 9 and 9+1=10
i.e 9 & 10.
Thus, when 9 is added to (2*10=20), the result is 29.
