Question : If the product of three consecutive numbers is 210, then the sum of the smaller number is:
Option 1: 3
Option 2: 5
Option 3: 4
Option 4: 11
Correct Answer: 11
Solution : Given that the product of three consecutive numbers is 210. Let the three consecutive numbers as $(n-1)$, $n$, and $(n+1)$. According to the question, $n(n+1)(n-1) = 210$ $⇒n^3-n-210=0$ $⇒(n-6)(n^2+6n+35)=0$ $n = 6$ and $n \notin \mathrm{R}$ Therefore, the three consecutive numbers are 5, 6, and
Question : Directions: In the following question, select the related number from the given alternatives. 520 : 738 :: ? : 350
Option 1: 220
Option 2: 222
Option 3: 230
Option 4: 248
Correct Answer: 222
Solution : Given: 520 : 738 :: ? : 350
First, find the cube of the number and add the same number to the resultant number. Like, 520 : 738→83 + 8 = 512 + 8 = 520; 93 + 9 = 729 + 9
Question : Which physical theory explains the generation of thrust by rocket engines, jet engines and deflating balloons?
Option 1: Newton's laws of motion
Option 2: Exclusion principle
Option 3: Faraday's laws of electromagnetic induction
Option 4: Laws of thermodynamics
Correct Answer: Newton's laws of motion
Solution : The correct option is Newton's laws of motion.
Newton's Third Law of Motion explains thrust generation. For rockets, burning fuel accelerates gases downward, propelling the rocket upward. In jet engines, air is drawn in, compressed, mixed with fuel, and ignited, producing a

Question : What is the value of $\frac{\sin (A+B)}{\sin A \cos B}$?
Option 1: $1 + \cot A \tan B$
Option 2: $1 + \tan A \cot B$
Option 3: $1 – \sin A \cos B$
Option 4: $1 − \cot A \tan B$
Correct Answer: $1 + \cot A \tan B$
Solution : $\frac{\sin (A+B)}{\sin A \cos B}$ = $\frac{\sin A \cos B + \cos A \sin B}{\sin A \cos B}$ = $1+ \cot A \tan B$ Hence, the correct answer is $1+ \cot A \tan B$.
