Top 50 MCQs - CBSE Class 10 Maths 2026 Top 50 MCQs – CBSE Class 10 Maths (2026) 1. If HCF(336, 54) = 6, then LCM(336, 54) is:
(a) 3024
(b) 1008
(c) 1512
(d) 2016
✅ Answer: (a) 3024 We use \( \text{HCF} \times \text{LCM} = a \times b \). So, \( \text{LCM} = \frac{336 \times 54}{6} = 3024 \). 2. The zeroes of the polynomial \( x^2 - 3 \) are:
(a) \( \sqrt{3}, -\sqrt{3} \)
(b) \( 3, -3 \)
(c) \( 0, 3 \)
(d) \( 1, -1 \)
✅ Answer: (a) \( \sqrt{3}, -\sqrt{3} \) Solve \( x^2 - 3 = 0 \Rightarrow x = \pm \sqrt{3} \). 3. The pair of equations \( 2x + 3y = 5 \) and \( 4x + 6y = 10 \) has:
(a) Unique solution
(b) No solution
(c) Infinitely many solutions
(d) None of these
✅ Answer: (c) Infinitely many solutions The second equation is exactly twice the first ⇒ coincident lines. 4. In an AP, if \( a = 5 \), \( d = 3 \), then \( a_{10} \) is:
(a) 30
