QMI 1500
OCT/NO 2017 MEMO
Question 1
( )
Multiplying the first bracket by the 2
( )
Multiplying everything by 12
(( ) ) ( )
Therefore x= 10
Option 3
Question 2
Option 3
Question 3
Option 2
, Question 4
Length: width
30cm: 20cm (for Book)
? (……): 90cm (for Table)
= 135cm
Area of Table =
= 135cm × 90cm
= 12 150
Option 1
Question 5
New visible length = 135-15-15= 105
New visible width = 90-15-15 = 60
Since the inner part has 8 of 15cm of the square:
New Perimeter = 2(105) + 2(60)+8(15)
= 210+120+120
= 450cm
Option 3
Question 6
Linear programming
There two types of gifts
Let type 1 be x and type 2 be y
We 2 machines: Machine A and machine B
For Machine A:
