Question : Directions: Select the option that is related to the first number in the same way as the third number is related to the fourth number and the fifth number is related to the sixth number. 13 : ? :: 8 : 512 :: 11 : 1331
Option 1: 729
Option 2: 2197
Option 3: 1728
Option 4: 4096
Correct Answer: 2197
Solution : Given: 13 : ? :: 8 : 512 :: 11 : 1331
Like, (8 : 512)→(83 = 512 (11 : 1331)→(11)3 = 1331 Similarly, follow the same pattern for (13 : ?)→(13)3 = 2197
Therefore, 2197 is the required answer. Hence, the
Question : Refer to the below data table and answer the following question.
Raw Materials and Interest are what percent of total expenses?

Solution : The correct choice is the fourth option.
Active voice emphasises the doer of the action, while passive voice emphasises the receiver. To convert passive to active, we make the subject perform the action and rephrase the verb.
The structure of
Question : AB is the diameter of a circle having a centre at O. PQ is a chord that does not intersect AB. Join AP and BQ. If $\angle$BAP = $\angle$ABQ, then ABQP is a:
Option 1: cyclic square
Option 2: cyclic trapezium
Option 3: cyclic rhombus
Option 4: cyclic rectangle
Correct Answer: cyclic trapezium
Solution : $\angle$BAP = $\angle$ABQ and AB $\neq$ PQ Now, $\angle$BAP + $\angle$BQP = 180° ⇒ $\angle$ABQ + $\angle$BQP = 180° ⇒ AB || PQ So, ABQP is a cyclic trapezium. Hence, the correct answer is cyclic trapezium.
Question : $\frac{1}{7}$+(999$\frac{692}{693})$×99 is equal to ___.
Option 1: 1
Option 2: 99000
Option 3: 99800
Option 4: 99900
Correct Answer: 99000
Solution : $\frac{1}{7}$ + (999$\frac{692}{693})$×99 = $\frac{1}{7}$ + $(\frac{692999}{693})$×99 = $\frac{1}{7}$ + $(\frac{692999}{7})$ = $\frac{693000}{7}$ = 99000 Hence, the correct answer is 99000.
Question : Directions: A series is given below with one term missing. Choose the correct alternative from the given ones that will complete the series. TU, DE, NO, ?
Option 1: PQ
Option 2: FG
Option 3: XY
Option 4: VW
Correct Answer: XY
Solution : Given: TU, DE, NO, ?
Add 10 to the positional value of each letter of the previous term to get the next term in the series. First letter of the series→T + 10 = D; D + 10 = N; N + 10 = X
Question : Directions: Which term from among the given options can replace the question mark (?) in the following series to make it logically complete? BV 101, (?), DX 109, EY 113, FZ 117
Option 1: CW 105
Option 2: CV 104
Option 3: CW 106
Option 4: CV 107
Correct Answer: CW 105
Solution : Given: BV 101, (?), DX 109, EY 113, FZ 117
Add 1 to the place value of the first and second letters and add 4 to the number, to obtain the next term – BV 101→B + 1 = C; V + 1 =
Question : The angle subtended by a chord on the major arc of the circle is 50°. What is the angle subtended by the same chord on the centre of the circle?
Option 1: 100°
Option 2: 120°
Option 3: 140°
Option 4: 25°
Correct Answer: 100°
Solution : The angle subtended by an arc at the centre is double the angle subtended by it at any point on the remaining part of the circle. Let O, R, and PQ be the centre, a point on the major arc, and the aforementioned chord, respectively.
Question : Directions: In a certain code language, BED is written as 122 and CAB is written as 37. How will ADD be written in that code language?
Option 1: 65
Option 2: 50
Option 3: 101
Option 4: 82
Correct Answer: 82
Solution : Given: BED is written as 122 –
Find the square of the sum of the position values of the letters of the given word BED then add 1 to the resultant number to obtain the required code – B→2; E→5; D→4 Now, find the square
