4th GRADE MATH PRACTICE QUESTIONS

Problem 1 :

On a sports day, 161 students are in the play ground. They are standing in 7 equal rows. How many students are in each row ?

(A) 35             (B) 38          (C) 23

Solution :

Total number of students  =  161

Number of rows  =  7

Number of students in each row  =  161/7

  =  23

In each row there will be 23 students.

Problem 2 :

Which of the following shape is circle ?

(A)  First object   (B)  Middle object   (C)  Last object

Solution :

The middle object is circle.

Problem 3 :

If one side of the square is having the length 6 cm then what is the perimeter of the square ?

(A) 10                   (B) 24                (C) 12

Solution :

Side length of square  =  6 cm

Perimeter of square  =  4 (side)

  =  4(6)

=  24 cm

So, the perimeter of the square is 24 cm.

Problem 4 :

Cody rides his bike to the park to meet a friend at noon. Cody arrives at the park at 11:00 a.m. Which question can be answered using this information ?

A. What is the distance between the park and Cody’s house ? 

B. How long could Cody have to wait for his friend ?

C. How long does Cody stay at the park ?

D. When will Cody leave to go home ?

Solution :

Cody rides the bike to the park to meet his friend in noon.

He reaches the spot at 11 am, so how long he has to wait for his friend. So option B is correct.

Problem 5 :

I have a liter of bottle of cola. I drink 650 ml, how much is left ?

(A)  250 ml   (B)  350 ml    (C)  1650 ml

Solution :

Quantity of cola initially  =  1 liter (1000 ml)

Quantity of cola i drank  =  650 ml

Remaining quantity  =  1000 - 650

 =  250 ml

Problem 6 :

What is the value of 3(x - 6), when x  =  11 ?

Solution :

To find the value of 3(x - 6) when x = 11, we apply the value of x in the expression. 

  =  3(11 - 6)

  =  3(5)

  =  15

Problem 7 :

At a wild life center adult entry is $12 and child entry is $8. I pay for 2 adults and 3 children with a $50 bill. How much change ?

Solution :

Cost of adult entry  =  $12

Cost of 2 adult tickets  =  2(12)  ==>  24

Cost of children ticket  =  $8

Cost of 3 children ticket  =  3(8)  ==>   24

   =  24 + 24

   =  48

Change  =  50 - 48

  =  $2

Problem 8 :

What is the mean of 13, 7, 8, 4 ?

Solution :

Mean  =  (13 + 7 + 8 + 4)/4

  =  32/4

  =  8

So, the mean is 8.

Problem 9 :

A rectangular swimming pool measures 5  1/2 meters by 3  1/2. What is the perimeter ?

Solution :

Length of the rectangular pool  =  5  1/2 meter ==>  11/2

Breadth of rectangular pool  =  3  1/2  ==>  7/2

Perimeter of the pool  =  2(l + b)

  =  2(11/2 + 7/2)

  =  11 + 7

  =  18 m

Problem 10 :

The ratio of lions to tigers in a zoo 1 : 3. If there are 4 lions, how many tiger will there be ?

Solution :

Number of lions  =  x

Number of tigers  =  3x

Number of lions (x)  =  4

Then number of tigers  =  3(4)  ==>   12
