# Total Prize Money CodeChef Solution

## Problem – Total Prize Money CodeChef Solution

In a coding contest, there are prizes for the top rankers. The prize scheme is as follows:

• Top 10 participants receive rupees X each.
• Participants with rank 11 to 100 (both inclusive) receive rupees Y each.

Find the total prize money over all the contestants.

#### Input Format

• First line will contain T, number of test cases. Then the test cases follow.
• Each test case contains of a single line of input, two integers X and Y – the prize for top 10 rankers and the prize for ranks 11 to 100 respectively.

#### Output Format

For each test case, output the total prize money over all the contestants.

#### Constraints

• 1 \leq T \leq 10001≤T≤1000
• 1 \leq Y \leq X \leq 10001≤YX≤1000

#### Sample 1:

Input: 4
1000 100
1000 1000
80 1
400 30
Output: 19000
100000
890
6700

#### Explanation:

Test Case 1: Top 10 participants receive rupees 1000 and next 90 participants receive rupees 100 each. So, total prize money = 10 \cdot 1000 + 90 \cdot 100 = 19000=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 \cdot 1000 + 90 \cdot 1000 = 100000=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 \cdot 80 + 90 \cdot 1 = 890=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 \cdot 400 + 90 \cdot 30 = 6700=10⋅400+90⋅30=6700.
