A card is drawn at random from a well-shuffled pack of 52 cards. Find the probability of getting a red king.

Total number of cards = 52

Number of red kings = 2

⇒ P(Getting a red king)

Find the value of (cos48° – sin42°).

Evaluate: (tan23°) × (tan67°)

In figure-1 are two arcs of concentric circles of radii 7 cm and 3.5 cm resp., with centre O. If ∠ POQ = 30°, then find the area of shaded region.

Two similar triangles ABC and PQR have their areas 25 cm² and 49 cm² respectively. If QR = 9.8 cm, find BC.

Divide (2x² – x + 3) by (2 – x) and write the quotient and the remainder.
