Question : Directions: In the following question, which one set of letters when sequentially placed at the gaps in the given letter series shall complete it? aa_a_b_abaa_
Option 1: abab
Option 2: baab
Option 3: baba
Option 4: abba
Correct Answer: baab
Solution : Given: aa_a_b_abaa_
To fill the series we have to divide the series→aa_ / a_b / _ab / aa_ Let's check each option – First option: abab; aaa / abb / aab / aab (No repeated pattern has been found.)
Question : Directions: Select the option figure in which the given figure is embedded. (Rotation is NOT allowed)
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : Since the rotation is restricted. So, the embedded figure will have the same orientation as the main figure. By comparison of all the option figures, the given question figure is embedded only in the first option figure.
Hence, the first option is correct.
Question : What is the value of $\frac{\cot \theta+\operatorname{cosec} \theta-1}{\cot \theta-\operatorname{cosec} \theta+1}$?
Option 1: $2 \sec \theta$
Option 2: $2 \operatorname{cosec} \theta$
Option 3: $2 \cot \theta$
Option 4: $\operatorname{cosec} \theta+\cot \theta$
Correct Answer: $\operatorname{cosec} \theta+\cot \theta$
Solution : Given, $\frac{\cot \theta+\operatorname{cosec} \theta-1}{\cot \theta-\operatorname{cosec} \theta+1}$ We know, $\operatorname{cosec^2}θ−\cot^2θ=1$ $=\frac{\cot \theta+\operatorname{cosec} \theta-(\operatorname{cosec^2}θ−\cot^2θ)}{\cot \theta-\operatorname{cosec} \theta+1}$ $=\frac{\cot \theta+\operatorname{cosec} \theta-(\operatorname{cosec}θ−\cotθ)(\operatorname{cosec}θ+\cotθ)}{\cot \theta-\operatorname{cosec} \theta+1}$ $=\frac{(\operatorname{cosec}θ+\cotθ)[1-(\operatorname{cosec}θ-\cotθ)]}{\cot \theta-\operatorname{cosec} \theta+1}$ $=\frac{(\operatorname{cosec}θ+\cotθ)[1-\operatorname{cosec}θ+\cotθ)]}{\cot \theta-\operatorname{cosec} \theta+1}$ $=\operatorname{cosec}θ+\cotθ$ Hence, the correct answer is $\operatorname{cosec}θ+\cotθ$.
Question : Directions: In the following question, four number pairs are given. In each pair, the number on the left side of (–) is related to the number on the right side of (–) with some Logic/Rule /Relation. Three pairs are similar based on the same Logic/Rule/Relation. Select the odd one out from the given alternatives. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. 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)
Option 1: 3241 – 5732
Option 2: 2354 – 4835
Option 3: 1326 – 3807
Option 4: 2345 – 4826
Correct Answer: 3241 – 5732
Solution : Let's check each option – First option: (3241 – 5732); 5732 – 3241 = 2491≠ 2481 Second option: (2354 – 4835); 4835 – 2354 = 2481 Third option: (1326 – 3807); 3807 – 1326 = 2481 Fourth option: (2345 – 4826); 4826 –
Question : Find out the wrong number in the sequence: 40960, 10240, 2560, 640, 200, 40, 10.
Option 1: 2560
Option 2: 200
Option 3: 640
Option 4: 40
Correct Answer: 200
Solution : Given series: 40960, 10240, 2560, 640, 200, 40, 10 The pattern is: 40960 ÷ 4 = 10240 10240 ÷ 4 = 2560 2560 ÷ 4 = 640 640 ÷ 4 = 160 ≠ 200 200 is the wrong number. The correct number is 160. 160
Question : Directions: 34 is related to 70 in a certain way. Following the same logic, 56 is related to 114. To which of the following is 23 related, following the same logic?
Option 1: 39
Option 2: 52
Option 3: 48
Option 4: 47
Correct Answer: 48
Solution : Given: 34 is related to 70 and 56 is related to 114.
To find the second number, add 1 to the first number and then multiply it by 2. Like, 34 is related to 70→34 + 1 = 35; 35 × 2 = 70 And,
