From 1 and 2 together:

L learns Maithili.

so, Statement 1 and 2 together are necessary.

Hence, option B is the correct answer.

Outer radius of track (R) =  = 17.5 m

Inner radius of track (r) =  = 14 m

Area of track = Π (R² – r²) = Π [(17.5)² – (14)²]

= 22 × 15.75 = 346.5 m²

Therefore, Cost of levelling = 346.5 × 8 = Rs. 2772

2 sin²θ + 5cosθ – 4 = 0

(2 – 2 cos²θ) + 5cosθ - 4 = 0

2 cos²θ - 5 cos θ + 2 = 0

2 cos²θ - 4cosθ – cos θ + 2 = 0

(2cos θ–1) (cos θ-2) = 0

Hence, cosθ =

θ = 60°

hence, cot θ + cosec θ = cot 60° + cosec 60°

• Sahrul is the main festival of the tribal population of Jharkhand. Sarhul means the ‘worship of Sal tree’.
• It is celebrated during spring season when the Sal trees get new flowers on their branches.

A body whose speed is constant might be accelerating.

● The reason is, speed is a scalar quantity but velocity is a vector quantity and rate of change of velocity is defined as acceleration.

● Hence even if speed is constant but if the body is moving in a variable direction it has variable velocity which leads to acceleration of a body.

● Best example is a body moving in a circular motion with constant speed, even though it’s speed is constant it doesn’t have a constant velocity as it’s velocity changes every moment and hence it also has acceleration.
