5. Amiya has 8 more stamps than Huiling. Ravi has twice as many stamps as Amiya. Amiya and Ravi have 72 stamps altogether. How many stamps does Huiling have?
Jawab:
Amiya = x
Huiling = y
Ravi = z
y = x - 8
z = 2x
x + z = 72
x + 2x = 72
3x = 72
x = 72/3 = 24
y = x - 8
y = 24 - 8 = 16
So, Huiling has 16 stamps

7. In last semester examination, syamil showed excellent results in three subjects. He got the same marks for English and Music, while 85 marks for Mathematics. If the total marks of the three subjects are 270, find the total marks obtained for Music.
English + Music + Math = 270
English + Music =
270 - Math = 270 - 85 = 185
Since he got same marks in English and Music, so 185 ÷ 2 = 92,5 each
Total marks obtained for Music = 92,5
Jawaban:
92,5
Penjelasan dengan langkah-langkah:
he got same marks for english n music (dia mendapat nilai yang sama di pelajaran inggris dan music)
85 marks for math (nilai 85 untuk mtk)
total marks of the three = 270 (total nilai = 270)
total nilai = English +Music+Math
English = Music = a
total nilai = a+a+85
270 = 2a+85
2a = 270-85
2a = 185
a = 185/2
a = 92,5
so total marks for Music is 92,5
8. of the candidates who sat for an international mathematics examination, 18% of the candidates obtained grade A, 38% obtained grade B and the rest obtained grade C. Given that 77 candidates obtained grade C, find the total number of candidates whi sat for the examination.
Jawab:
175
Penjelasan dengan langkah-langkah:
44/100 = 77/X (44/100 or 44% equals to 77 people per X people)
0,44/77 = 1/X (0,44 is 44 divided by 100, then 77 pindah ruas)
77/0,44 = X (ruasnya dibalik agar mendapat nilai X)
175 = X (Hasilnya 175, jadi 44% dari 175 adalah 77)
jadi keseluruhan kandidat yang duduk pada ujian matematika international berjumlah 175

Manakala, jika priya memberikan wang RM35 kepada Ravi Ravi akan mempunyai wang dua kali ganda priya. Adakah Ravi mempunyai lebih banyak wang daripada priya? Berikan alasnnya ... Bleh Bantu?
Kita misalkan Ravi = R; Priya = P
—Jika Ravi beri RM40, jumlah keduanya sama

R = P + 80
R > P
P + 80 > P
Wang Ravi lebih banyak daripada Priya karena wang Ravi = wang Priya + RM80.

16. 2 Ahmad's Continual Assessment results slip was accidentally tom. Part of his mathematics and science marks are missing. 83 785 English Mother Tongue Mathematics Science Average al 75 a) b) What could possibly be Ahmad's marks in mathematics? What could possibly be Ahmad's marks in science?
Jawab:
a. 70 to 79
b. 60 to 69
Penjelasan dengan langkah-langkah:
average = 75
sum = 4 × 75 = 300
english + mother tongue = 83 + 78 = 161
so
math + science = 300 - 161 = 139
then
if
mat = 70 → science = 69
mat = 71 → science = 68
...
mat = 79 → science = 60
so
possibly mat → 70 to 79
possibly science → 60 to 69
and its not help anything
