Correct Answer: $0$

Solution : We know that $\sec (90°+ \theta) = –  \ \text{cosec}\; \theta$ and $\text{cosec} \;(90°+\theta) = \sec \theta$
$\cos 47^\circ \sec 133^\circ + \sin 44^\circ \ \text{cosec}\;136^\circ $
$=\cos 47^\circ \sec (90^\circ + 43^\circ) + \sin 44^\circ \ \text{cosec} \;(90^\circ + 46^\circ) $
$=-\cos 47^\circ \text{cosec}\;43^\circ

Correct Answer: (16, 43, 22)

Solution : Given:
(11, 33, 17); (18, 44, 21)

Add 5 to the sum of the first and the third numbers to get the second number. 
⇒ (11, 33, 17)→(11 + 17) + 5 = 33
⇒ (18, 44, 21)→(18 + 21) + 5 =

Correct Answer: 31

Solution : Given:
42 : 20 :: 64 : ?

Subtract 2 from the first number and then divide it by 2 to obtain the second number of each pair.
Like, 42 : 20→(42 – 2) ÷ 2 = 40 ÷ 2 = 20
Similarly, follow the

Correct Answer: BADC

Solution : The fourth option is the correct choice.

The sequence begins with sentence B, introducing a man wandering in the village at night. Sentence A follows, stating that he heard robbers planning a robbery at the moneylender's house. Sentence D comes next, describing how he

Correct Answer: 0.3 metre

Solution : Given: The lengths of the two pipes are 1.5 m and 1.2 m.
HCF of (1.5, 1.2) = HCF of ($\frac{15}{10}, \frac{12}{10}$) = $\frac{3}{10}$ = 0.3
So, the greatest length of the pipe of the same size that can be cut from these two

Correct Answer: CH₃COOH

Solution : The correct answer is CH₃COOH.

Among the carboxylic acids, Acetic acid (CH₃COOH), also referred to as Ethanoic acid, is crucial. Acetic acid is produced by fermentation and oxidation of natural carbohydrates, resulting in a diluted solution known as Vinegar

Correct Answer: 2

Solution : Given: $a+\frac{1}{a} = 2$
If we take $a=1$, then LHS = $1+\frac{1}{1}=2$ = RHS
So, $a=1$ satisfies the equation.
Now, $a^5+\frac{1}{a^5}=1^5+\frac{1}{1^5}=2$
Hence, the correct answer is 2.
