First, solve the original puzzle:
- If Deepa is truth-teller -> exactly one liar -> p2 and p3 are truth-tellers.
Then p2 (truth) says 'Deepa and Sunil same type' - true (both truth) - consistent.
p3 (truth) says 'at least one truth-teller' - true - consistent.
Solution: Deepa=T, Pooja=T, Sunil=L

Now, hypothetically assume Deepa is liar instead of truth-teller.
Then we need to re-solve:
- Deepa liar -> statement 1 false -> number of liars is NOT exactly one -> 0, 2, or 3 liars.
- If 0 liars, all truth-tellers. Then Deepa truth - contradicts Deepa liar.
- If 2 liars, then Pooja and Sunil are liars. Then Pooja liar says 'Deepa and Sunil same type' - Deepa liar, Sunil liar -> same type -> true statement, but liar can't make true - contradiction.
- If 3 liars, all are liars. Then Pooja liar says 'Deepa and Sunil same type' - both liars -> same -> true statement - contradiction.
- Therefore, no consistent assignment exists when Deepa is liar.
Thus, if we hypothetically assume Deepa is liar, there would be ZERO truth-tellers.
