there’s no serial for this question
Serial?
I forgot the serial!
From the video the ans is x/6
Those markings are done by greg btw
What does “serial” mean?
I don’t know the question no
That’s fine - tell us your approach and attempt to this one.
I don’t get how you got x from your steps?
That is not enough, because all of x, 1.5x and \frac{2x}{3} must be an integer. Also the HCF cannot be more than the smallest number.
Oh I get it but how did you get to x/6 from that ?
Let’s try with an example. Suppose x = 6; what do you get then?
6, 9, 4
And what’s the HCF in that case?
The hcf is 1
Using that test case itself, can you find the answer?
Are you saying that you should try to take 1/6 common?
Can that work? Recall that x is a multiple of 6, so what can you say about \frac{x}{6}?
So I understand we just have to take a number common in such a way that the other terms still remain as intergers.
I still didn’t understand the choosing no approach though.
Here I just converted every term to intergers and got x/6 as the ans
Which is indeed a correct approach.
