Correct Answer: $90^\circ$

Solution :
In $\triangle PQR$, PN is the median.
So, QN = NR
and PN = QN (given)
In $\triangle PQN$
PN = QN
Let $\angle QPN=\angle NQP = \theta$
Similarly, In $\triangle PNR$
PN = NR
Let $\angle NPR = \angle NRP = \alpha$
$\therefore QPR=\theta

Correct Answer: 16978.50 cm²

Solution : Arc length = 23.1 cm
⇒ $\frac{\theta}{360^{\circ}}× 2\pi r$ = 23.1
⇒ $\frac{18^{\circ}}{360^{\circ}}× 2\pi r$ = 23.1
⇒ $r=73.5$ cm
Area of circle = $\pi$r$^{2}$ = ${\frac{22}{7}}\times{73.5}\times{73.5}$ = 16978.50 cm$^{2}$.
Hence, the correct answer is 16978.50 cm².

Correct Answer: 25 percent

Solution : The cost of each pen (CP) = $\frac{1}{25}$
The selling price of each pen (SP) = $\frac{1}{20}$P
Profit per pen = Selling Price per pen − Cost Price per pen = $(\frac{1}{20}) – (\frac{1}{25}) = (\frac{1}{100})$
⇒ Profit Percentage = $\frac{\text{Profit}}{\text{Cost price}}×100$ = ($\frac{\frac{1}{100}}{\frac{1}{25}})×100$

Correct Answer: Pulses

Solution : The correct answer is Pulses.

Correct Answer: Electron

Solution : The correct answer is electron.

In Quantum Mechanics, dual nature of a particle theory was given de Broglie in 1924. He said that when a particle is moving it exhibits both the particle nature and the wave nature. Electrons also exhibit the property of both

Correct Answer: $10 \frac{10}{19}$%

Solution : Let the actual cost of 1 m cloth be $x$
The false cost price of 1.05 m cloth = $x$
So, the false cost price of 1 m cloth = Rs. $\frac{x}{1.05}$
The actual selling price of 1 m cloth = Rs. $x$
The

Correct Answer: INR 2000

Solution : Since the efficiency is inversely proportional to the time taken.
The ratio of efficiencies of Rani, Priya, and Guddu $=\frac{1}{10}:\frac{1}{12}:\frac{1}{15} = 6:5:4$
So, the share of Priya = $\frac{5}{15}$ × 6000 = INR 2000
Hence, the correct answer is INR 2000.

Correct Answer: 70

Solution : The correct answer is 70.
