Question 1 :
Which is the least 6 digit number of the following numbers
(A) 100050 (B) 100095 (C) 10000
Solution :
Comparing the above three numbers, 100050 is the least 6 digit number.
Question 2 :
The sum of two integers is 48. If one of the integer is -24, determine the other
(A) 62 (B) 72 (C) 24
Solution :
Sum of two integers = 48
One of the integer = -24
Let x be the unknown
x + (-24) = 48
x = 48 + 24
x = 72
Question 3 :
Every prime number except 2 is an __________ number.
(A) Odd (B) Even (C) Composite
Solution :
2 is the only even prime number.
Question 4 :
Find the ratio of 250 kg to 10 kg.
(A) 25 : 1 (B) 15 : 50 (C) 1 : 25
Solution :
= 250 : 10
= 25 : 1
So, the ratio between 250 kg to 10 kg is 25 : 1
Question 5 :
Solve the equation
3x - 4 = 4 - (8 + 3x)
(A) 5 (B) 2 (C) 0
Solution :
3x - 4 = 4 - (8 + 3x)
3x - 4 = 4 - 8 - 3x
3x - 4 = -4 - 3x
3x + 3x = -4 + 4
6x = 0
x = 0
So, the answer is 0.
Question 6 :
A dot gives us an idea of a _____________
(A) Ray (B) Point (C) Line
Solution :
A dot gives an idea of point.
Question 7 :
Diameter of the circle is 12 cm. Find its radius?
(A) 4 cm (B) 6 cm (C) 8 cm
Solution :
Radius is half of the diameter.
Radius = Diameter / 2
= 12/2
Radius = 6 cm
Question 8 :
Find the perimeter of the rectangle having length and breadth are 16 cm and 8 cm respectively.
(A) 24 cm (B) 76 cm (C) 48 cm
Solution :
Length of the rectangle = 16 cm, breadth = 8 cm
Perimeter of the rectangle = 2 (l + b)
= 2(16 + 8)
= 2(24)
= 48 cm
Question 9 :
Solve for x, x - 3 = 11
(A) 14 (B) 8 (C) 1
Solution :
x - 3 = 11
x = 11 + 3
x = 14
So the answer is 14.
Question 10 :
If the sum of two angles measures 90° then the angles are known as __________ angles.
(A) Complementary (B) Supplementary (C) Zero
Solution :
If sum of the two angles is 90 then they are known as complementary angles.
