## Maximum Capacity CodeChef Solution ## Problem

A building lift has a maximum capacity of 500 kilograms.
However, due to the pandemic, at most 8 people can use the lift at once.

There are  friends, each having a weight of  kilograms. Find whether all of them can use the lift at once.

### Input Format

• The first line of input will contain a single integer , denoting the number of test cases.
• Each test case contains two space-separated integers  and  — the number of friends and the weight of each friend.

### Output Format

For each test case, output on a new line, YES, if all friends can use the lift at once. Otherwise, output NO.

You may print each character in uppercase or lowercase. For example, NOnoNo, and nO, are all considered the same.

• 1≤�≤1000
• 1≤�,�≤100

### Sample 1:

Input

Output

4
7 75
8 50
10 10
5 100

NO
YES
NO
YES


### Explanation:

Test case 1: The total weight of all friends is 7⋅75=525. Since the total weight is greater than the maximum capacity, all of them cannot use the lift at once.

Test case 2: The total weight of all friends is 8⋅50=400. Since the number of friends is ≤8 and the total weight is less than the maximum capacity, all of them can use the lift at once.

Test case 3: The total number of friends is greater than 8. Thus, all of them cannot use the lift at once.

Test case 4: The total weight of all friends is 5⋅100=500. Since the number of friends is ≤8 and the total weight is  maximum capacity, all of them can use the lift at once. ## SOLUTION
