View Answer
Correct choice: C
Explanation:
Maximum earning will be only when he will won on the maximum yielding table. A ----> 10:1 B ----> 20:1 C ----> 30:1 i.e, he won on B and C but lost on A 20 x 200 + 30 x 200 -1 x 200 = 9800 minimum earning will be when he won on table A and B and lose on that table 3. Therefore, 10 x 200 + 20 x 200 - 1 x 200 = 6000-200 = 5800 Therefore, Difference= 9800 - 5800 = 4000
