"Aamir comes home at half-past one."

Translation: आमिर डेढ़ बजे घर आता है।

[mayateacher]

Here डेढ़ बजे is correct. But in another exercise it is incorrect, so DUO please fix this.

[nunya186503]

I believe baje is correct in adverbial cases (what the call "oblique"?), like "doing sth AT half past one," whereas baja is correct when you're simply saying what time it is now, i.e., "it IS half past one."

[pradeepan90]

Why preposition not used?
Like डेढ़ बजे पर or डेढ़ बजे में

[PrakharBav]

time in hindi does not use postpostions like पर or में when you are indicating a exact time frame
