Explanation

Test Case 1: Top 10 participants receive rupees 1000 and next 90 participants receive rupees 100 each. So, total prize money = 10 . 1000 + 90 . 100 = 19000.

Test Case 2: Top 10 participants receive rupees 1000 and next 90 participants receive rupees 1000 each. So, total prize money = 10 . 1000 + 90 . 1000 = 100000.

Test Case 3: Top 10 participants receive rupees 80 and next 90 participants receive rupee 1 each. So, total prize money = 10 . 80 + 90 . 1 = 890.

Test Case 4: Top 10 participants receive rupees 400 and next 90 participants receive rupees 30 each. So, total prize money = 10 . 400 + 90 . 30 = 6700.
