can anyone help me !!  唔識做...help....

suppose hk's money supply (in$billion) on a day was:

total issue of legal tender        100
legal tender held by all deposit-taking institution   20
demand deposit                         200
deposits with licensed banks  600
negotiable certificates of deposit (NCDs) issued by licensed banks and held by public      150
deposits with restricted licensed banks  (RLBs) and deposit-taking  companies (DTCs)   180
NCDs issued by RLBs and DTCs                                        120
NCDs issued by RLBs and DTCs and held by the public  40

1) calculate M1,M2 and M3 respectively.
2) Suppose on the next day, some customers withdrew $30bilion from their savings deposits. They used $10 billion to buy NCDs from restricted licensed banks  and deposited $15 billion into their time deposit accounts with licensed banks  . They held the remaining $ 5 billion in cash. How did the above transaction affect M1, M2 and M3 respectively?

thank you!!!!

1.
M1=currency in circulation+demand deposit
=(100-20)+200
=280

*currency in circulation=total issue of legal tender-legal tender held by all deposit-taking institution (ie. reserve)

M2=M1+all deposit in licensed bank
=280+[(600-200)+150]
=830

*200 was included in demand deposit

M3=all money in HK
=830+(180+40)
=1050

*only NCDs held by public should be included

2.
M1: +$5bil
M2: -$30bil (withdraw from saving deposit) + $5bil (increased in M1) + $15bil (deposit in bank)
M3: no change, as nothing was remitted to overseas
