Dion membeli 20 Kg beras jenis A seharga Rp. 6.000,00/Kg dan 30 Kg beras jenis B dengan harga Rp. 4.000,00/Kg. kedua jenis beras tersebut kemudian dicampur. Agar Dion mendapat untung 4%, maka beras tersebut dijual seharga ..../Kg
Answer (4)
Answer: The correct option is (B) less than 2.
**Step-by-step explanation: **Given that Y varies directly with X and has a constant rate of change of 6.
We are to** find the possible value of X when the value of Y is 11.**
Since Y varies directly with X, so we can write
Y ∝ X ⇒ Y = k x ( i ) , [where ’k’ is the constant of variation]
Since the rate of change is constant and is equal to 6, so we must have
k = 6.
So, from equation (i), we have
Y = k X ⇒ Y = 6 X ( ii )
Now, when Y = 11, then from equation (ii), we get
Y = 6 X ⇒ 11 = 6 X ⇒ X = 6 11 < 6 12 = 2 ⇒ X < 2.
Thus, the value of X is less than 2 when Y = 11.
Option (B) is CORRECT.

Now, when Y = 11, then from equation (ii), we get
Thus, the value of X is less than 2 when Y = 11.
Option (B) is CORRECT. ;
The value of X when Y is 11 and varies directly with X at a constant rate of 6 is approximately 1.83. Therefore, the correct option is that X could be less than 2. The other options are not valid based on the direct variation relationship.
