In this section, we will see some practice problems for 6th grade students.

Question 1 :

Which is the least 6 digit number of the given number.

(A) 100050        (B) 100095       (C) 10000

Solution :

In the given number is 100050.

Question 2 :

The sum of two integers is 48. If one of the integer is -24, determine the other

(A) 62       (B) 72        (C) 50

Solution :

Let x and y be two integers

x + y  =  48

One integer is -24.

-24 + y  =  48

y  =  48 + 24

y  =  72

Hence the required number is 72.

Question 3 :

Every prime number except 2 is an __________ number.

(A) Odd         (B) Even          (C) Fraction

Solution :

The only even prime number is 2. Other than all are odd.

Question 4 :

Find the ratio of 250 kg to 10 kg

(A) 25 : 1        (B) 1 : 25         (C) 1 : 5

Solution :

=  250 : 10

By simplifying this, we get 25 : 1.

Question 5 :

Solve the equation

3x - 4 = 4 - (8 + 3x)

(A) 7       (B) 0        (C) -7

Solution :

3x - 4  =  4 - (8 + 3x)

3x - 4  =  4 - 8 - 3x

3x + 3x  =  -4 + 4

6x  =  0

x  =  0/6

x  =  0

Question 6 :

A dot gives us an idea of a _____________

(A) ray         (B) point        (C) line

Solution :

A dot gives us an idea of a point.

Question 7 :

Diameter of the circle is 12 cm. Find its radius?

(A) 4 cm        (B) 6 cm        (C) 8 cm

Solution :

Diameter of the circle  =  12 cm

Question 8 :

Find the perimeter of the rectangle having length and breadth are 16 cm and 8 cm respectively.

(A) 55 cm         (B) 39 cm        (C) 48 cm

Solution :

Perimeter of rectangle  =  2 (l + b)

length  =  16 cm and breadth  =  8 cm

Perimeter  =  2(16 + 8)

=  2(24)

=  48 cm

Question 9 :

Solve for x, x - 3  =  11

(A) 14        (B) 17        (C) 15

Solution :

x - 3  =  11

x  =  11 + 3

x  =  14

Question 10 :

If the sum of two angles measures 90° then the angles are known as __________ angles.

(A) Complementary        (B) Supplementary angles

(C) Zero angle

Solution :

Complementary angles will have the sum 90 degree.
