both are different meanings.. 1 why were you playing with him (tum uske sath kyu khel rhe the) past continuous tense 2 why did you play with him (tum uske sath kyu khele the) past indefinite tense

sorry, your question is not clear to understand...

past indefinite tense .....rohan wrote a letter .....she helped the poor .....they played cricket (this tense shows the work done in past)

if you had known the way to go there ,you would not talk about going there
