Qn. 2 [ 5 m ]

Peter went shopping with just enough money to buy 11 books.

However, he only bought 8 and spent the rest of his money on a total of 24 files and pens. The ratio of the number of files to the number of pens he bought was 3:5. Each pen cost 80 cents. Each file cost 40 cents more than a pen.

How much did he spend on the books he bought?

No of files (3 units)           

8 units → 24

1 unit → 24 ÷ 8 = 3       

3 units →3 X 3 = 9

 No of pens (5 units)                       

5 × 3 = 15

 Cost of files           

9 X 1.20 = $10.80

 Cost of pens          

15 X 0.80 = $12

 Total cost               

10.80 + 12.00 =22.80                                                                                     

Since she bought only 8 books,

cost of 3 books = cost of 24 files and pens

Cost of 8 books

3 books → $22.80                                    M1

1 book  → $7.60

8 books → $7.60 X 8 = $60.80                M1   A1

Qn. 3 [ 5 m ]

38% of the people in a banquet were men.

27% of the people were women and the rest were children.

a) If there were 120 more children than women, how many people were there at the banquet?

b) Some of the women left the banquet and as a result, the number of men was twice the number of woman. How many women left the banquet?

 (a)             Percentage of children

100% – 38% – 27% = 35%              M1

 Difference in percentage

35% – 27% = 8%

 No of people (100%)

          8% →  120

         1% →  120 ÷ 8 = 15

          100% →  15 × 100 = 1500               A1                       

(b)              No of men (38%)

          1% → 120 ÷ 8 = 15

         38% → 38 × 15 = 570

 No of women (27%)

         27 × 15 = 405

 No of women who were still at the banquet

        0.5 x 570 = 285              M1                                               

No of women who left the banquet

        405 – 285 = 120           A1

Qn. 4 [ 5 m ]

Jie Wei stacked up some rectangular blocks as shown below.

a)      How many blocks are needed to form the 30^th layer?

b)      Which layer will have 37 blocks?

c)      Jie Wei stacked 50 layers altogether and painted the whole figure with some yellow paint. How many rectangular blocks have only 4 surfaces painted yellow?

 a)      Identify the pattern

          1^st layer → 1 + 0  blocks

          2^nd layer → 2 + 1 blocks

          3^rd layer→ 3 + 2 blocks

 Therefore, 30^th layer

30 + 29 blocks = 59 blocks  M1   A1

 b)      Going by the pattern,

37 blocks→ 19 + 18

 ANS :  19^th layer                           A1

 c)      From the figure, every layer except layer 1 and layer 50 will have 2 blocks with 4 surfaces painted

 No. of affected layers

50 – 2 = 48

           No. of blocks with 4 surfaces painted

Roadside ER by Hal Karp -December 2006

Dr Scott Kurtzman had left his house early enough to allow for the inevitable traffic on the way to deliver an 8 am lecture at the University of Connecticut. By 7.30, the 50-year-old surgeon had joined the hundreds of commuters filtering through one of the state’s busiest and dangerous junctions.

Kurtzman moved into the far right lane, preparing to turn right at the junction. The light changed to red. A short line of cars was stopped in front of him.

As he waited, Kurtzman was alarmed to see a dump truck barrelling down the hill on the other side of the intersection. The driver was going too fast – he had clearly lost control.

The truck swerved to avoid the cars up ahead. But the sudden weight shift heaved the fully loaded vehicle off balance. With six tyres on the ground and the other six high in the air, the rig hurtled down the road, straight at the intersection.

Thanks to years of emergency room experience, Kurtzman promptly shifted into trauma mode and drove onto a patch of grass alongside the road. An instant later, the dump truck was on its side, plowing into vehicle after vehicle as it slid through the stoplight. Fifty metres farther, the skidding stopped and the truck suddenly burst into flames.

Kurtzman jumped out of his car and ran towards the burning truck but the temperature was volcanic and the driver was dead. But alongside the rig, he spotted a small car, folded up like an accordion. Inside, a woman was covered in blood and glass. He yanked on her door, but it felt welded shut. Directly behind, flames from the truck licked the woman’s car, and within moments, fire shot out from underneath it.

Flames had reached the backseat, and the door still wouldn’t open. The policeman tossed Kurtzman his pocketknife, and he sawed at the woman’s seat belt until it finally gave way. The others quickly pulled her out.

After about 90 minutes, when all 16 victims had been triaged and taken to area hospitals, Kurtzman climbed quietly into his car and drove to the university’s medical school. After swapping his blood-soaked clothes for scrubs, he delivered his lecture – two hours late.

The crash had involved 20 vehicles and killed four people, two of whom the doctor had not seen. “A person with my skills simply can’t drive by someone who’s injured,” says Kurtzman. “I refuse to live my life that way.”

Philippines: Through the Fire

Mars W. Mosqueda Jr.

Nine-year-old Antonio ”Dan Boy” Fernandez Jr was playing with his younger brother Ken in their yard last June when he noticed smoke billowing from the roof of their house in Cebu’s Carcar city. Realising that his five-year-old brother Nathaniel was napping inside, Dan Boy shielded his head from the falling embers with his hands and rushed inside the wooden house.

”I was so scared to see the flames on the roof but when I heard my brother cry, I just closed my eyes and rushed in,” says Dan Boy, who stopped schooling two years ago to look after his younger brothers.

He found his brother sitting in the corner of the room, frightened and crying. Nathaniel was disoriented from the smoke, so Dan Boy grabbed him with his right hand. ”Don’t worry, kuya (big brother) is here,” Dan Boy said as he shielded Nathaniel from the flames with his own body.

Just as they reached the front door, Nathaniel stopped. A protruding nail had caught his shorts. Flames licked the upper portion of the door as Dan Boy struggled to get his brother free. With one last, desperate tug they ran into the yard as the fire devoured the property.

For his heroic act, Dan Boy received financial assistance from the government and concerned individuals, as well as a scholarship from a university in Cebu City.

Passage 2

Sri Lanka: Croc Attack

Vijitha Yapa September 2007

R.M. Jayasiri Bandara wanted to make the most of his medical leave from the Sri Lankan army last September. He took his wife Srimathi and three-year-old daughter to the Maragaha Tank near Anuradhapura, a 2200-year-old city in Sri Lanka’s north central province.

There, they left their daughter on the bicycle seat to go for a quick dip. Srimathi waded waist deep into the cool water while Bandara immersed himself fully. But after only a few dips, he heard a scream. Jumping up, he saw that his daughter was fine but there was no sign of his wife. He shouted her name but there was no response.

Then Bandara spotted churning water and bubbles nearly three metres away. Splashing his way towards the disturbance, a sharp object struck his leg and his worst fear was confirmed: A crocodile had taken his wife. Bandara dove into the two-metre-deep pond, searching blindly until he found its slimy tail. He grabbed hold but the three-metre-long creature shook him off. He tried again, catching the croc around its body.

Bandara became desperate when the croc would not let go of his wife. He then remembered a local belief that tickling the croc’s belly will make it open its mouth. He tried it and amazingly, the beast wriggled and opened its mouth, freeing his wife.

Bandara grabbed Srimathi from the crocodile’s jaws and threw the 60-kilogram croc as far as he could. When she reached out to drag him to shore, Srimathi realised that half her right arm was missing.

For his brave deed, R.M. Jayasiri Bandara was awarded the Gold Medal for Civilian Bravery by Sri Lanka’s Foundation for Civilian Bravery at a ceremony in Colombo on June 14, 2007.
