Calculating Percentages And Showing In Separate Columns

SELECT DISTINCT CASE WHEN SM.SERVICE_TYPE_N = 1 THEN 'LABORATORY'
WHEN SM.SERVICE_TYPE_N = 2 THEN 'PODIATRY'
WHEN SM.SERVICE_TYPE_N = 3 THEN 'ADMINISTRATION'
WHEN SM.SERVICE_TYPE_N = 4 THEN 'DIET'
WHEN SM.SERVICE_TYPE_N = 5 THEN 'DENTAL'

In the above query i need to calculate 100%,30% and percentage other than 100 and 30 and show them in separate columns how to do that?

1)ROUND(SUM(BM.CONCESSION_AMOUNT_M),2)AS [100_PERCENT]
WHERE BM.BILL_AMOUNT_M=BM.CONCESSION_AMOUNT_M

2)ROUND(SUM(BM.CONCESSION_AMOUNT_M),2)AS [30_PERCENT]
WHERE AND BM.CONCESSION_AMOUNT_M=BM.BILL_AMOUNT_M * 0.30

3) ROUND(SUM(BM.CONCESSION_AMOUNT_M),2)AS [OTHER_CONCESSION_PERCENT]
WHERE BM.CONCESSION_AMOUNT_M between BM.BILL_AMOUNT_M*0.001 and BM.BILL_AMOUNT_M*0.299
OR BM.CONCESSION_AMOUNT_M between BM.BILL_AMOUNT_M*0.301 and BM.BILL_AMOUNT_M*0.999
