Well, I'm not sure of the ans as I'm only p4
This is my method;
A+84=A*5
S+16=A+84
166+84=20
So,
1 unit-> 200/4=50
50+116=Ans(166)

If he gave away 84 Singapore Stamps, there will be an equal amount of Singapore and Australian Stamps.

Singapore [1][2][3][4][5]
Australia [1][2][3][4][5]

116 - 84 = 32

After giving 32 more steps,

Singapore [1]
Australia [1][2][3][4][5]

Therefore,
4 u = 32
5 u = 32/4 x 5
= 40

Total singapore stamps = 40 +84
= 124
