Question 1
1 / -0

The breadth of a rectangle is w cm and the length is 5 times as long as its breadth. What is the perimeter of the rectangle?

A
5w²cm

B
12w cm

C
(10 + 2w) cm

D
(25 + w²) cm

Solution

We have, breadth = w cm ∴ Length = 5w cm So, perimeter=2(5w + w) = 2 × 6w = 12w cm
Question 2
1 / -0

If a = b, then ax =________.

A
a + x

B
bx

C
b − x

D
b ÷ x

Solution

If a = b, then ax = bx
Question 3
1 / -0

Twelve less than 3 times a number is 27. The number is ________.

A
29

B
39

C
65

D
13

Solution

Let the number be x. According to question, 3x − 12 = 27 ⇒ 3x = 39 ⇒x = 39/3 = 13
Question 4
1 / -0

Equation for the statement Thrice the length(l) of a room is 340 metres' is ________.

A
3l = 430

B
3l = 340

C
3 + l = 340

D
3l + 340 = 0

Solution

Let l be the length of a room. ∴3l = 340
Question 5
1 / -0

Power of a variable in a linear equation is

A
Zero

B
One

C
Two

D
Three

Solution

Power of a variable in a linear equation is One
Question 6
1 / -0

To get the value of ′y′, the number to be multiplied on either side of equation y/10 = 3/2 is _________.

A
-10

B
10

C
3

D
0

Solution

We have, y/10 = 3/2
⇒10 × y/10 = 10 × 3/2 ⇒ y = 15
Question 7
1 / -0

The number of girls in a class is 3 times the number of boys. Which of the following cannot be the total number of students in the class?

A
24

B
32

C
36

D
41

Solution

Let the number of boys be x. ∴ Number of girls = 3x If x + 3x=41 ⇒ 4x = 41 ⇒ x = 41/4 And we know that the number of students can't be in fraction.
Question 8
1 / -0

The algebraic expression for the statement 'thrice of x is added to y multiplied by itself' is _______.

A
3x + 2y

B
3x + y²

C
3 (x + y²)

D
3x + y

Solution

3 (x) + y × y = 3x + y²
Question 9
1 / -0

If 3/4 x + 8 = 17, then the value of x is _________.

A
-12

B
36

C
12

D
-36

Solution

We have, 3/4 x + 8 = 17 ⇒ 3/4 x = 17 − 8 = 9 ⇒ x = 9 × 4/3 = 12
