As per statement given, n=1.5k
n+k=5
Let's Assume, If k=2; n=3 n+k=5. Sufficient.

n=3; OA is B

Statement: 2n = 3k
Hence: n = 1.5k
Now, n+k =5
2.5k = 5
Hence k = 2
Therefore, n must be 3
OA is B

Hi Dillesh4096,
You got the correct answer but you wrote the wrong option.
N=3 is option B not D. You may want to correct the typo. Thanks.
