I. Challenging problems.
1. Xin Yu weighs 34.6 kg. Jia Wang is 2.65 kg lighter than Xin Yu and 5 kg lighter than Xian Zhi. Find Xian Zhi's mass.
34.6-2.65kg = 31.95kg
31.95 + 5 = 36.95 kg
Xian Zhi's mass is 36.95kg.
2. A flag pole is 5.82 m long. The carpenter sawed it into 3 pieces of equal length. Find the length of each piece. (Round off to 1 decimal place.)

The length of each piece is 2.0m.
4. Ms Lim had 8.2 m of cloth. She used 1.25 m to sew 1 dress. If she sewed 6 dresses, how many metres of cloth had she left?
1.25 x 6 = 7.5
8.2 – 7.5 = 0.7 m
She had 0.7m left.
5. If 8 litres of petrol cost $8.64. How much is 1 litre of petrol?
8.64 ÷ 8 = $1.08
1 litre of petrol cost $1.08.
6. Kassandra bought 2 chickens. One chicken weighed 2.9 kg and the other is 0.4 kg heavier. If the price of the chicken is $0.90 per kg, how much did she pay for the 2 chickens?
2.9 + 0.4 = 3.3 kg (the mass of the heavier chicken)
3.3 + 2.9 = 6.2 kg (total mass of 2 chickens)
6.2 x 0.90 = $5.58
2 Chickens cost $5.58.
7. Xuen Qing had $10. He bought 9 pencils at $0.25 each. He used the rest of his money to buy 5 pens. What is the price of each pen?
9 x 0.25 = 2.25
10 – 2.25 = 7.75
7.75 ÷ 5 = $1.55
Each pen cost $1.55.

3.
(a) 10 + 5 + 6 + 3 + 4+ 8 = 36cm
(b) 8 x 4 = 32 square cm
5 x 6 = 30 square cm
30 + 32 = 62 square cm
4.
Perimeter = 10 + 8 + 10 + 8 + 5 + 5 = 46 cm
Area
10 x 8 = 80 square cm(Area of ABCH)
5 x 3 = 15 square cm(Area of FEDG)
80 – 15 = 65 square cm
5.
Length = 3 units
2 lengths = 3 x 3 = 6 units
1 breadth = 1 unit
2 breadths = 2 units
6 units+ 2units = 32 cm
32 ÷ 8 = 4
Length = 4 cm x 3 = 12 cm
Breadth = 4 cm
Area = 12 x 4 = 48 square cm
6.
105 x 30 = 3150 square cm
70 x 30 = 2100 square cm
35 x 30 = 1050 square cm
3150 + 2100 + 1050 = 6300 square cm

English Unit 11 Comprehension Passage and answers.
Revisit the revision entry http://idependentlearner.blogspot.com/2007/08/erevision-english-16807.html before looking at the answers below.

Unit 11 (Text type - Information Report)
The camel - once a wild animal, was domesticated about 4000 - 6000 years ago. For thousands of years, it has been an essential part of the lives of people living in the deserts of Asia and Africa. This "ship of the desert" can travel great distances ferrying people and loads of goods across hot deserts.
Besides being a beast of burden, the camel is in many other ways useful to desert dwellers. It is a source of food in terms of meat and milk. Its hair and hide can also be used to make necessary things such as tents, blankets, scandals, rugs and clothing. Dried camel droppings are also used as fuel.
There are basically two species of camels. The first is the single-humped camel, also known as the dromedary or Arabian camel while the second is the Bactrian, or Asian camel, which has two humps. The camel's hump consists of fat and muscle without any bone. It is hard and upright when the camel is given enough food and water. If the camel has to go without food and water for a period of time, it can be nourished for a few days by the fat stored in the hump, but the hump will then become limp and lean to one side.
1. What is the camel popularly known as?
Answer: It is known as "the ship of the desert".
2. Why is it so called?
Answer: It can ferry people over great distances and carry loads of goods across hot deserts.
3. Name two ways the camel is useful to desert dwellers?
Answer: (Any two of the following.) It is a source of food. Its hair and hide can be used to make useful things. Its droppings can be used as fuel.
4. Name one difference between the Arabian camel and the Bactrian camel?
Answer: The Arabian camel has one hump while the Bactrian camel has two humps.
5. When does the camel's hump become limp?
Answer: It becomes limp when the camel goes without food and water for a period of time and the fat in the hump is used up.

Unit 10 (Text type - Personal Recount)
When my alarm clock rang at 6.00 am, I drowsily stumbled out of bed. I put my drowsiness down to having stayed up studying for the maths exam until almost midnight. 'Serves you right,' I thought. 'Next time, don't leave your revision until the last minute.'
Having forced down a slice of toast and half a cup of milk, I barely made it to the bus stop in time to catch my usual bus. On the way to school, I dozed off. If one of my classmates hadn't been on the bus and woken me up to get off, I might have missed the stop completely.
Ms Ritchie, my teacher, looked at me rather strangely as she handed out the examination papers. "Are you okay, Susan?" she asked. "Yes, I think so," I said. When I looked at her, I had to blink, because she seemed a bit blurry around the edges. So did the printing on the examination paper, when I turned it over. A drop of water plopped onto the paper, followed by another. It seemed to be coming from my face. I felt as hot as fire; the next minute, I was shivering violently with cold.

Unit 10 (Text type - Personal Recount)
When my alarm clock rang at 6.00 am, I drowsily stumbled out of bed. I put my drowsiness down to having stayed up studying for the maths exam until almost midnight. 'Serves you right,' I thought. 'Next time, don't leave your revision until the last minute.'
Having forced down a slice of toast and half a cup of milk, I barely made it to the bus stop in time to catch my usual bus. On the way to school, I dozed off. If one of my classmates hadn't been on the bus and woken me up to get off, I might have missed the stop completely.
Ms Ritchie, my teacher, looked at me rather strangely as she handed out the examination papers. "Are you okay, Susan?" she asked. "Yes, I think so," I said. When I looked at her, I had to blink, because she seemed a bit blurry around the edges. So did the printing on the examination paper, when I turned it over. A drop of water plopped onto the paper, followed by another. It seemed to be coming from my face. I felt as hot as fire; the next minute, I was shivering violently with cold.
