(a) 5 + x + 2
(b) 2x + 5
(c) 2x − 5
(d) 5x + 2

Solution:

The option (b) is correct answer.

5 more than twice a number x is written as 2x + 5.

2. The quotient of x by 2 is added to 5 is written as
(a) x/2 + 5
(b) 2/x+5
(c) (x+2)/ 5
(d) x/ (2+5)

Solution:

The option (a) is correct answer.

The quotient of x by 2 is added to 5 is written as x/2 + 5.

3. The quotient of x by 3 is multiplied by y is written as
(a) x/3y
(b) 3x/y
(c) 3y/x
(d) xy/3

Solution:

The option (d) is correct answer.

It can be written as

x/3 × y = xy/3

4. 9 taken away from the sum of x and y is
(a) x + y − 9
(b) 9 − (x+y)
(c) x+y/ 9
(d) 9/ x+y

Solution:

The option (a) is correct answer.

9 taken away from the sum of x and y is x + y – 9.

5. The quotient of x by y added to the product of x and y is written as
(a) x/y + xy
(b) y/x + xy
(c) xy+x/ y
(d) xy+y/ x

Solution:

The option (a) is correct answer.

The quotient of x by y added to the product of x and y is written as x/y + xy.

6. a2b3 × 2ab2 is equal to
(a) 2a3b4
(b) 2a3b5
(c) 2ab
(d) a3b5

Solution:

The option (b) is correct answer.

It can be written as

a2b3 × 2ab2 = 2a2 × a × b3 × b2 = 2a3b5.

7. 4a2b3 × 3ab2 × 5a3b is equal to
(a) 60a3b5
(b) 60a6b5
(c) 60a6b6
(d) a6b6

Solution:

The option (c) is correct answer.

It can be written as

4a2b3 × 3ab2 × 5a3b = 4 × 3 × 5 × a2 × a × a3 × b3 × b2 × b = 60a6b6

8. If 2x2y and 3xy2 denote the length and breadth of a rectangle, then its area is
(a) 6xy
(b) 6x2y2
(c) 6x3y3
(d) x3y3

Solution:

The option (c) is correct answer.

We know that area of a rectangle = length × breadth

By substituting the values

Area = 2x2y × 3xy2 = 6x3y3

9. In a room there are x2 rows of chairs and each two contains 2x2 chairs. The total number of chairs in the room is
(a) 2x3
(b) 2x4
(c) x4
(d) x4/2

Solution:

The option (b) is correct answer.

We know that

Total number of chairs in the room = Number of rows × Number of chairs

By substituting the values

Total number of chairs in the room = x2 × 2x2 = 2x4

10. a3 × 2a2b × 3ab5 is equal to
(a) a6b6
(b) 23a6b6
(c) 6a6b6
(d) None of these

Solution:

The option (c) is correct answer.

It can be written as

a3 × 2a2b × 3ab5 = 2 × 3a3 × a2 × a × b × b5 = 6a6b6
