Question

How did you reach here? which type of sentence​

Answer 1

Answer:

interrogative sentence

Answer 2

Answer:

Explanation:

Grammatically yes. A complete interrogative sentence.

But, the correctness of the tense, largely, depends upon the context, where it's being used.

“I reached”. “Where did you reach?”

“Once, long back, after a field trip, we got lost on the way back home.” “And, where did you reach?”

Usually, when we use simple past tense to talk about things that happened in the past, we also specify the time of the action by way of some past indicators. ( Yesterday, last week, long ago etc.)
