Answers :
1) Answer: C
General formula,
2) Answer: C
3) Answer: A
ATQ,
π (r²) × 25 = 3850
r² = 49
r = 7 cm
4) Answer: A
5) Answer: C
6) Answer: A
7) Answer: C
From Euler’s Formula
Vertices – Edges + Faces = 2
Vertices – 30 + 12 = 2
Vertices = 20
8) Answer: A
(x + y)² = x² + y² + 2xy
(x + y)² = 100 + 2 × 22
(x + y)² = 144
x + y = √144 = 12
9) Answer: D
Go by options,
Only Eqn. [4x² + 8x + 4 = 0] has equal roots.
10) Answer: C
