Bath in Winters Solution Codechef
A geyser has a capacity of X litres of water and a bucket has a capacity of Y litres of water. One person requires exactly 2 buckets of water to take a bath. Find the maximum number of people that can take bath using water from one completely filled geyser.
Input Format
- First line will contain T, number of test cases. Then the test cases follow.
- Each test case contains a single line of input, two integers X,Y.
Output Format
For each test case, output the maximum number of people that can take bath.
Constraints
- 1≤T≤1000
- 1≤X,Y≤100
Sample Input 1
4
10 6
25 1
100 10
30 40
Sample Output 1
0
12
5
0
Explanation
- Test Case 1: One bucket has a capacity of 6 litres. This means that one person requires 2⋅6=12 litres of water to take a bath. Since this is less than the total water present in geyser, 0 people can take bath.
- Test Case 2: One bucket has a capacity of 1 litre. This means that one person requires 2⋅1=2 litres of water to take a bath. The total amount of water present in geyser is 25 litres. Thus, 12 people can take bath. Note that 1 litre water would remain unused in the geyser.
- Test Case 3: One bucket has a capacity of 10 litres. This means that one person requires 20⋅10=20 litres of water to take a bath. The total amount of water present in geyser is 100 litres. Thus, 5 people can take bath. Note that 0 litres of water would remain unused in the geyser after this.
