Sample Input 3 100 400 1000 1200 100 450 1000 1350 150 400 1200 1200 Sample Output 13 13 11 Explanation 1000 - 100 TestCase 1: Number of coconuts of Type A required: coconuts of Type B required = 1200 = 3. So the total number of coconuts required is 10+ 3 = 13. 400 TestCase 2: Number of coconuts of Type A required coconuts of Type B required 1350 450 required is 10+ 3 = 13. 1000 100 3. So the total number of coconuts 1200 400 = 10 and number of = = 10 and number of 1200 8 and number of TestCase 3: Number of coconuts of Type A required 150 coconuts of Type B required= = 3. So the total number of coconuts required is 8 +3 = 11.
