Explanation

Junaid starts with Rs. 600.

He gives one-fourth (1/4) to Awais:

Amount given to Awais = 600 * (1/4) = Rs. 150

Remaining amount = 600 - 150 = Rs. 450

He then gives half of the remaining amount to Hamza:

Amount given to Hamza = 450 * (1/2) = Rs. 225

Remaining amount = 450 - 225 = Rs. 225

The amount left with Junaid is:

Rs. 225

Explanation

A consonant cluster is a group of two or more consonants at the beginning of a word without any vowels between them.

In "Spring," the cluster "spr" is a consonant cluster.

Explanation

Let's simplify the expression:

tanθ + cotθ

= sinθ/cosθ + cosθ/sinθ

= (sin²θ + cos²θ) / (sinθcosθ)

Since sin²θ + cos²θ = 1:

= 1 / (sinθcosθ)

= 1/sinθ * 1/cosθ

= cosecθ * secθ

= secθcosecθ

Explanation

Owls have an exceptional hearing range, typically between 200 Hz and 12,000 Hz.

This range helps them detect high-frequency sounds, crucial for locating prey in low light conditions.

l = 45 cm

r = 9 cm

θ = l / r

= 45 / 9

= 5 radians
