parent123 how did you do the geometry question?? i(im a student, just took it today) found it impossible. the othter questions were easy to me but i had no idea about the geometry question. i spent like 1 hour looking at it(im not exxagerating) oh and good luck on chinese tmr!!

180degrees/3=60degrees
60degrees/3=30degrees
180degrees-30degrees=150degrees

this is my solution for q17. hope its the one you are asking for

0

Isn't 60degrees/3=20degrees?

Chocolate Cookies : Almond Cookies
3 : 1
= 30 : 10

30units / 6 = 5units ( left )

Left:

Chocolate Cookies : Almond Cookies
30 : 10
5 : 3

30u + 10u = 40u
40u / 5 = 8u ( cookies left )
8u - 5u ( chocolates left ) = 3u ( almonds left )
10u - 3u = 7u ( Almonds sold )

7u -> 210
1u -> 30
25u + 7u = 32u
32 x 30 = 960cookies
