# Free Playing with Numbers 01 Practice Test - 4th Grade

### Question 1

(18×50)+(18×9)=18×?

18

95

59

9

#### SOLUTION

Solution :C

Applying Distributive property of multiplication over addition to simplify:

(18×50)+(18×9)

=18×(50+9)=18×59

### Question 2

Which is greater: 50 tens 5 ones OR 4 hundreds, 9 tens and 9 ones?

50 tens 5 ones

4 hundreds 9 Tens 9 ones

Both are equal

5 tens 50 ones

#### SOLUTION

Solution :A

50 Tens 5 Ones = 50×10+5×1=500+5=505

4 Hundreds, 9 Tens 9 Ones = 4×100+9×10+9×1=400+90+9=499

505>499

Hence, 50 Tens 5 Ones is greater.

### Question 3

State True or False:

When the last 2 digits of a number are divisible by 4, the number is also divisible by 4.

True

False

#### SOLUTION

Solution :A

The divisibility rule for a number to be divisible by 4 is that the last 2 digits of the number should be divisible by 4.

For e.g: In 1328 the last 2 digits = 28, which is exactly divisible by 4.

→ 1328÷4=332, with a remainder of 0.

Hence 1328 is exactly divisible by 4.

### Question 4

State True or False:

7245 is divisible by 6.

True

False

#### SOLUTION

Solution :B

A number is divisible by 6 if it is divisible by both 2 and 3.

In 7245: sum of the digits is = 7 + 2 + 4 + 5 = 18, which is divisible by 3.

If a number is even, it is divisible by 2.

Here 7245 is an odd number, hence it is not divisible by 2.

∴ 7245 is not divisible by 6.

### Question 5

28 =_____ x 4

5

6

7

8

#### SOLUTION

Solution :C

28 = 7 x 4

### Question 6

What will be the divisor when 38 is divided by 9?

38

9

4

2

#### SOLUTION

Solution :B

Divisor is a number by which another number is divided.

Here, 38 is divided by 9.

Hence, 9 is the divisor.

### Question 7

Which side of the number line should we move while subtracting?

Right

Left

Down

Up

#### SOLUTION

Solution :B

Subtraction means to take away or remove. We count backwards while subtracting. Hence, on the number line, we move left.

For e.g: 9−3=6

### Question 8

Find the value.

3221−789=?

2255

2522

2331

2432

#### SOLUTION

Solution :D

11 11 2/1/1 11 /3/2/2 /1 − 7 8 9 ––––––––––––– 2 4 3 2

### Question 9

Find the value.

56+35=?

91

81

811

5635

#### SOLUTION

Solution :A

1 5 6+ 3 5 ––––––– 9 1The value is 91.

### Question 10

There are 88 students going on a trip in 4 school buses. Each bus has equal number of students. How many students are there in each bus?

22

23

24

25

#### SOLUTION

Solution :A

Given:

Number of students going on a trip = 88

Number of school buses = 4

If there are an equal number of students in each bus, then

The number of students in each bus = 88÷4=22

There are 22 students in each bus.
