Question :
The type of tail found in Shark is:
Option 1:
Protocercal
Option 2:
Homocercal
Option 3: Hetrocercal
Option 4: Diphycercal
Correct Answer: Hetrocercal

Sharks have a heterocercal tail structure. Heterocercal tails have an asymmetrical form, with the top lobe of the tail being bigger and extending further than the lower lobe. This shape gives sharks lift and stability in the water, which helps
Question : If $\sin \theta-\cos \theta=\frac{1}{5}$, then find the value of $\sin \theta+\cos \theta$.
Option 1: $\frac{5}{7}$
Option 2: $\frac{7}{5}$
Option 3: $\frac{5}{3}$
Option 4: $\frac{3}{5}$
Correct Answer: $\frac{7}{5}$
Solution : Given, $\sin \theta-\cos \theta=\frac{1}{5}$ Squaring both sides, we get, $\sin^2 \theta+\cos^2 \theta -2\sin \theta \cos \theta=\frac{1}{25}$ $⇒1-2\sin \theta \cos \theta=\frac{1}{25}$ $⇒2\sin \theta \cos \theta=\frac{24}{25}$ Adding 1 with both sides, we get, $⇒\sin^2 \theta+\cos^2 \theta +2\sin \theta \cos \theta=1+\frac{24}{25}$ [$\because \sin^2 \theta+\cos^2 \theta=1$] $⇒(\sin \theta+\cos \theta)^2=\frac{49}{25}$
Question : Which of the following metals is used in spacecrafts to withstand high temperatures?
Option 1: Fe
Option 2: Ti

Question : A dishonest dealer defrauds to the extent of $x$% in buying as well as selling his goods by using a faulty weight. What will be the gain percentage on his outlay?
Option 1: $2x$%
Option 2: $\left (\frac{10}{x} +x^{2}\right )$%
Option 3: None of these
Option 4: $\left (x+\frac{x^{2}}{100} \right)$%
Correct Answer: None of these
Solution : Given: A dishonest dealer defrauds to the extent of $x$% in buying as well as selling. Let the total cost of an article be Rs. 100. The cost price (CP) of that article for the dishonest dealer = Rs. (100 – $x$) The
