Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the following sets. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. For example -operations on 13 such as adding/subtracting/multiplying etc.13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

Question : Find the value of $\cos 47^\circ \sec 133^\circ + \sin 44^\circ \text{cosec}\; 136^\circ $.
Option 1: $\frac{1}{2}$
Option 2: $1$
Option 3: $0$
Option 4: $–1$
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

E.g. 13 – operations on 13 such as adding/subtracting/multiplying, etc., to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is NOT allowed.) (11, 33, 17) (18, 44, 21)
Option 1: (12, 40, 18)
Option 2: (7, 32, 9)
Option 3: (16, 43, 22)
Option 4: (15, 34, 19)
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 =
Question : Directions: In the following question, select the related number from the given alternatives. 42 : 20 :: 64 : ?
Option 1: 31
Option 2: 32
Option 3: 33
Option 4: 34
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

Question : Two pipes of lengths of 1.5 m and 1.2 m are to be cut into equal pieces without leaving any extra length of pipes. The greatest length of the pipe pieces of the same size that can be cut from these two lengths will be:
Option 1: 0.13 metre
Option 2: 0.4 metre
Option 3: 0.3 metre
Option 4: 0.41 metre
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
Question : What is the chemical formula of vinegar?
