The sum of three numbers are 6. Each number is increased by 20 and the new numbers are multiplied by 10. What is the sum of the resulting numbers?

Starting out we only know that their sum is 6 (so we cannot assume they are integers or consecutive, etc).
j%2Bk%2Bl=6

j%2Bk%2Bl=6

New numbers are
%28j%2B20%29%2A10=10j%2B200

%28j%2B20%29%2A10=10j%2B200

%28k%2B20%29%2A10=10k%2B200

%28l%2B20%29%2A10=10l%2B200

New sum:
