In Korea, there are four kinds of coins – a 10-won coin, a 50-won coin, 100-won coin and a 500-won coin.
Given K 10-won coins, L 50-won coins, M 100-won coins and N 500-won coins, you are to write a program that calculate the total amount.
Input
The input consists of T test cases. The number of test cases T is given in the first line of the input file. Each test case will consist of four integers K, L, M and N (0<K, L, M, N>100). The integers given in a line are separated by a space.
Output
Print exactly one line for each test case. For each test case of K, L, M and N you should output the total amount.
The following shows sample input and output for three test cases.
