Algebra Puzzle 2

This is actually easier than the 3x3 :)

Algebra Puzzle

Let's say that p=Pumpkin, u=Umbrella and a=Apple.
p+u+p=45
u+u+p=36
a+a+a=9
9÷3=3
a=3
p+u+a=30
u+u+a=21
p+p+a=39
p+p+a-a=39-3
=36
p+p=36
p=36÷2
=18
u+u+p-p=36-18
=18
u+u=18
u=18÷2
=9

Hence,
a=3
p=18
u=9

Pumpkin Pie

The crumbly batter broke down beautifully in my mouth,the warm buttery paste spreading out over my tingling mouth. Spices wafted into my nose,warming it up in a second. The differentiated spices danced merrily in my mouth,and the familiar bursts of pumpkin settled in. In a moment,everything was gone.

Biology Test

今天的测验,真令人感到担忧。
翻开考卷:残了,复习了错的东西。。。
做完考卷:看到的一幕真的很像世界末日。。。
交上考卷:发现我已经能想像到分会卷子的恐怖情景。。。
同学们,你们也改是这么想把。

Prime Factorisation (continues...)

#25
2^4 X 3^5 X 7^2 X 11=2X2X2X2X3X3X3X3X3X7X7X11=2095632
Since the number ends with an even number, it should be divisable by 2.
First,I would divide in by 2. The answer would be 1047816.
2X1047816=2095632
1047816 would be a factor which is greater than 100.
It can also be divided by 4.
4X523908=2095632
It can also be divided by 6.
6X349272=2095632
The final answer-1047816,523908,349272.

#26
2 X 3^2 X 7^3 X 13=80262
3 X 7^2 X 13^3 X 17=5490303
The HCF of this two numbers is 1911.
From the working, I can find out that 7 and 13 are also common factors.
The final answer is-1911,7,13.
