Correct Answer: Pacific Ocean

Solution : The correct answer is the Pacific Ocean.

El Nino is a climate phenomenon characterised by unusually warm surface waters in the eastern tropical Pacific Ocean. When the eastern tropical Pacific's coastal waters warm (El Nino), the air pressure above the ocean falls. Increased

Correct Answer:

Solution : As per mirror image properties, closer things appear close to the mirror in reflection.
According to the information provided, if the mirror is placed on the right side of the figure (on line AB), the right of the reflected image will appear as the left, and

Correct Answer: $\frac{1}{8}$

Solution : Given:
$x+3y=-3x+y$
Solution:
⇒ $x+3y+3x-y=0$
⇒ $4x+2y=0$
⇒ $2(2x+y)=0$
⇒ $2x+y=0$
⇒ $y=–2x$
Put the value of $y$ in $\frac{x^{2}}{2y^{2}}$
= $\frac{x^{2}}{2(–2x)^{2}}$
= $\frac{x^{2}}{8x^{2}}$
= $\frac{1}{8}$
Hence, the correct answer is $\frac{1}{8}$.

Correct Answer: $1$

Solution : $\cot A = 1= \cot 45°$
$\therefore A = 45°$
$\sin B = \frac{1}{\sqrt{2}}=\sin45°$
$\therefore B = 45°$
$\sin (A+B) = \sin 90° = 1$
$\cot (A+B) = \cot 90° = 0$
$\therefore \sin (A+B) -\cot (A+B) =1-0= 1$
Hence, the correct answer is $1$.

Correct Answer: (5, 8, 19)

Solution : Given:
(7, 12, 25); (6, 9, 21)

The logic here is – (The first number + The second number + 6) = The third number
(7, 12, 25)→7 + 12 + 6 = 19 + 6 = 25
(6, 9, 21)→6 + 9

Correct Answer: Ghana Vadya

Solution : The correct answer is Ghana Vadya.

Ghana vaidyas, or idiophones, are solid instruments known for their rhythmic functions and do not require tuning before playing. These instruments, considered the earliest inventions by humans, were initially an extension of the human body, including items like

Correct Answer: 10.5 cm

Solution : The volume of hemisphere = $2425 \frac{1}{2} \mathrm{~cm}^3$
Volume of Hemisphere = $\frac{2}{3} × \pi r^3$
⇒ $\frac{2}{3} × \frac{22}{7} × r^3 =  \frac{4851}{2} \mathrm{~cm}^3$
⇒ $r^3 = 1157.63$
⇒ $r = 10.5$ cm
$\therefore$ The correct answer is 10.5 cm.
Hence, the correct

Correct Answer: 30

Solution : $\tan (4α − 50°)$ = $\cot (50° − α)$ = $\tan(90°–(50° − α))$
⇒ $\tan (4α − 50°)$ = $\tan(90°–(50° − α))$
⇒ $(4α − 50°) = 90°–(50° − α)$
⇒ $4α − 50° = 40°+α$
⇒ $3α = 90°$
⇒ $α = 30°$
Hence,

Correct Answer: Tamil Nadu

Solution : The correct answer is Tamil Nadu

Uttar Pradesh Hockey secured an undefeated streak in the 11th Hockey India Junior Men National Championship 2021, clinching the title with a 3-1 win over Hockey Chandigarh in the final at Kovilpatti, Tamil Nadu. Sharda Nand Tiwari, the

Correct Answer: 2302

Solution : Given: $\left(x+\frac{1}{x}\right)=5 \sqrt{2}$
Squaring both sides, we get,
⇒ $(x+\frac{1}{x})^2=(5 \sqrt{2})^2$
⇒ $x^2+\frac{1}{x^2}+2=50$
⇒ $x^2+\frac{1}{x^2}=48$
Again squaring both sides, we get:
⇒ $(x^2+\frac{1}{x^2})^2=48^2$
⇒ $x^4+\frac{1}{x^4}+2=2304$
$\therefore x^4+\frac{1}{x^4}=2302$
Hence, the correct answer is 2302.
