Class10|| Section A || Sample Question Paper-2023 In this video we will learn the solutions of SectionA(Q1 to Q10) of the sample paper 2023 with tips. 1. Let a and b be two positive integers such that a = p3q4 and b = p2q3 , where p and q are prime numbers. If HCF(a,b) = pmqn and LCM(a,b) = prqs, then (m+n)(r+s)= 2. Let p be a prime number. The quadratic equation having its roots as factors of p is 3. If α and β are the zeros of a polynomial f(x) = px2– 2x + 3p and α + β = αβ, then p is 4. If the system of equations 3x+y =1 and (2k-1)x +(k-1)y =2k+1 is inconsistent, then k = 5. If the vertices of a parallelogram PQRS taken in order are P(3,4), Q(-2,3) and R(-3,-2), then the coordinates of its fourth vertex S are 6. ∆ABC~∆PQR. If AM and PN are altitudes of ∆ABC and ∆PQR respectively and AB2: PQ2 = 4 : 9, then AM: PN = 7 .If x tan 60°cos 60°= sin60°cot 60°, then x = 8. If sinθ + cosθ = √2, then tanθ + cot θ = 9. In the given figure, DE ∥ BC, AE = a units, EC =b units, DE =x units and BC = y units. Which of the following is true? 10. ABCD is a trapezium with AD ∥ BC and AD = 4cm. If the diagonals AC and BD intersect each other at O such that AO/OC = DO/OB =1/2, then BC =
