Cookie Monster:

Daniel, 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 = 7/12

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

(i) How much does Alice have? (3 Marks)
(ii) How much do Alice & Cynthia have together? (1 Mark)

A 3u
(B+C) 1u

Total = 438+62 = 500

3u + 1u --> 500
4u --> 500
1u --> 125

3u = 3*125 = 375

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

This question isnt very difficult. All you need to do is to link up the relationship between the toy cars and toy soliders.
