Chinese = 0.75 = 3/4 = 9/12
Eurasians = 1 - 2/12 - 9/12 = 1/12
Malays 2u
Chinese 9u
Eurasians 1u
Total 12u
0.5*2u + 0.6*1u --> 68
1.6u --> 68
1u --> 42.5
Total 12u --> 12*42.5 = 510 -

In the end
A 1u
B 1u+50
total stamps = 487+119 = 606
1u + 1u + 50 --> 606
2u --> 556
1u --> 278
No of stamps must be removed from Box A & put into Box B = 487 - 278 = 209 -

F 7u
Total 12u
D 1u ---------->2u
(E+F) 5u ----->10u

i)
D = 1/6
ii)
D 2u
E 7u
F 12u - 2u - 7u = 3u
3u - 2u = 1u
1u --> 12
No of chocolates were there in the box = 12u = 12*12 = 144 -

A 3uAlice and Bernice have a total of $438. Cynthia has $62.The amount of money Alice has is trice the total of Bernice & Cynthia.
(i) How much does Alice have? (3 Marks)
(ii) How much do Alice & Cynthia have together? (1 Mark)
(B+C) 1u
Total = 438+62 = 500
3u + 1u --> 500
4u --> 500
1u --> 125
3u = 3*125 = 375
i) The amount of money Alice has $375
ii)
Alice $375
Cynthia $62
Alice + Cynthia = $375 + $62 = $437 -

24 sheep and hens are grazing in a field.These animals have a total of 70 legs. Find the number of sheep in the field.
Assume all animals are hens , hens = 24 , total no of legs = 24*2 = 48
the difference of legs between actual and assumption = 70 - 48 = 22
the difference of legs between 1 sheep and 1 hen = 2
the number of sheep = 22 / 2 = 11
