There are 487 stamps in Box A & 119 stamps in Box B. How many stamps must be removed from Box A & put into Box B so that Box B will have 50 more stamps than Box A? (4 Marks)
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 -
Cookie Monster:
F = 7/12Daniel, Elizabeth & Fenny shared a box of chocolates. Daniel's share was 1/5 of what Elizabeth & Fenny received. Elizabeth got 7/12 of the chocolates. Fenny got 12 more chocolates than Daniel.
(i) What fraction of the box of chocolates was Daniel's share? (2 marks)
(ii) How many chocolates were there in the box? (2 marks)
F 7u
Total 12u
D 1u ---------->2u
(E+F) 5u ----->10u
Total 6u ------>12u
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 -
Cookie Monster:
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 -
Cookie Monster:
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 -
