Hello Nikhil,
Again this is one the most common doubts of the students in the hire purchase concept as they often get confused in preparing books for hirer and hire vendor.
So in this question if you are making entries in the books of hirer, then for the down payment you will have to Debit the account of hire vendor in your books. So, in this case the hire vendor's account will be Debited.
Hope it helps.
Good Luck!
