# PROBLEM:

Find the number of \text{Rs. } 500 bills needed to pay an equivalent amount to N \text{ Rs. } 2000 bills.

# EXPLANATION:

We know 2000 = 500 \times 4.

So, 4 bills of \text{Rs. } 500 are needed to cover for one \text{Rs. } 2000 bill.

Thus, N bills of \text{Rs. 2000} will require 4N bills of \text{Rs. 500}.

# TIME COMPLEXITY

\mathcal{O}(1) per testcase.
