Linear Equations in One Variable | Class 8 Maths | NCERT Solutions

Q1.	Ncert Class 8 Maths Mcq Questions The root of the equation (2x – 1) + (x – 1) = x + 2 is
	A. 1
	B. 2
	C. -1
	D. -2.

Ans: 2
Hint:
(2x – 1) + (x – 1) = x + 2
⇒ 2x = 4 ⇒ x = \(\frac{4}{2}\) = 2.

Q2.	CBSE Class 8 Maths Chapter 2 Mcq The root of the equation
	A. 1
	B. 2
	C. 3
	D. 6.

Ans: 6.
Hint:
13x – 14 = 9x + 10 ⇒ 13x – 9x = 10 + 14
⇒ 4x = 24 ⇒ x = \(\frac{24}{4}\) = 6

Q3.	CBSE Class 8 Maths Chapter 2 Mcq Questions The root of the equation 11x – 5 – x + 6 = 2x + 17 is
	A. 1
	B. 2
	C. 3
	D. 4.

Ans: 2
Hint:
11x – 5 – x + 6 = 2x + 17
⇒ 8x = 16 ⇒ x = 2.

Q4.	CBSE Class 8 Maths Linear Equations in One Variable Mcq The root of the equation \(\frac{2}{3}\) y = \(\frac{5}{12}\) is
	A. \(\frac{8}{5}\)
	B. \(\frac{5}{8}\)
	C. 5
	D. 8

Ans: \(\frac{5}{8}\)
Hint:
\(\frac{2}{3}\) y = \(\frac{5}{12}\)
⇒ y = \(\frac{5}{12}\) × \(\frac{3}{2}\) = \(\frac{5}{8}\)

Q5.	CBSE Class 8 Maths Mcq Questions The root of the equation 7 (x – 1) = 21 is
	A. 1
	B. 2
	C. 3
	D. 4.

Ans: 4.
Hint:
7 (x – 1) = 21 ⇒ x – 1 = \(\frac{21}{7}\) = 3
⇒ x = 4.

Q6.	CBSE Class 8 Maths Linear Equations in One Variable Mcq Questions The root of the equation \(\frac{3}{2}\) x = – 27 is
	A. 6
	B. 12
	C. 18
	D. -18

Ans: -18
Hint:
\(\frac{5}{12}\) x = -27 ⇒ x = –\(\frac{27×2}{3}\) = -18.

Q7.	Class 8 Maths Mcq Chapter 2 If two angles are complementary and one angle is 10° greater than the other, then the smaller angle of the two is
	A. 40°
	B. 50°
	C. 90°
	D. 180°.

Ans: 40°
Hint:
x° = (90° – x°) + 10°
⇒ 2x° = 100° ⇒ x° = 50°
⇒ 90° – x° = 40°.

Q8.	Class 8 Maths Mcq online test If two angles are supplementary and one angle is double the other, then the larger angle is
	A. 60°
	B. 90°
	C. 120°
	D. 180°.

Ans: 120°
Hint:
x° + 2x° = 180° ⇒ 3x° = 180°
⇒ x° = 60° ⇒ 2x° = 120°

Q9.	Class 8 Maths Mcq with answers Twice a number is as much greater than 30 as the three times of the number less than 60. The number is
	A. 6
	B. 9
	C. 12
	D. 18.

Ans: 18.
Hint:
2x – 30 = 60 – 3x ⇒ 5x = 90
⇒ x = 18.
