Question : Directions: Prince drives 6 km towards the east from point A, takes a right turn, and drives 3 km. He again takes a right turn and drives 8 km. He takes one more right turn and drives 3 km to reach point B. How far and towards which direction should he drive to reach point A again?
Option 1: 4 km towards the west
Option 2: 2 km towards the north
Option 3: 2 km towards the east
Option 4: 4 km towards the south
Correct Answer: 2 km towards the east
Solution : Firstly, we will draw the diagram as per the given instructions –
Here, A is the starting point, and B is the endpoint. So, the distance between the starting point and the endpoint is AB. AB = 8 – 6 = 2
So, he had to travel 2 km towards the east to reach point A. Hence, the third option is correct.
Question : When did the Soviet Union disintegrate into 15 independent Republics?
Option 1: 1990
Option 2: 1991
Option 3: 1992
Option 4: 1993
Correct Answer: 1991
Solution : The correct answer is 1991.
On December 26, 1991, the Soviet Union underwent dissolution, resulting in the formation of 15 separate and sovereign republics. This significant occurrence signified the official demise of the USSR and paved the way for the establishment of independent nations like Russia, Ukraine, Belarus, Kazakhstan, and several more. The fall of the Berlin Wall started a series of events that led to the disintegration of the Soviet Union. This was also the year when a major financial reform was started in India.
Question : Directions: In a code language, WINNER is written as XJOOFS, and RALLY is written as SBMMZ. How will CARTOON be written in that language?
Option 1: DBSOPPU
Option 2: CAPTOON
Option 3: DBSUPPO
Option 4: CAPNOOT
Correct Answer: DBSUPPO
Solution : Given: WINNER is written as XJOOFS, and RALLY is written as SBMMZ.
Add 1 to each letter of WINNER, to obtain the required code – W + 1 = X; I + 1 = J; N + 1 = O; N + 1 = O; E + 1 = F; R + 1 = S Thus, WINNER is coded as XJOOFS. And, RALLY is written as SBMMZ. R + 1 = S; A + 1 = B; L + 1 = M; L + 1 = M; Y + 1 = Z Thus, RALLY is coded as SBMMZ. Similarly, follow the same pattern for CARTOON – C + 1 = D; A + 1 = B; R + 1 = S; T + 1 = U; O + 1 = P; O + 1 = P; N + 1 = O
So, CARTOON is coded as DBSUPPO. Hence, the third option is correct.

Question : Directions: In the following question, find the odd number pair from the given alternatives.
Option 1: 24 – 6
Option 2: 48 – 12
Option 3: 72 – 24
Option 4: 44 – 11
Correct Answer: 72 – 24
Solution : Let's check the options – First option: 24 – 6; 24 ÷ 6 = 4 Second option: 48 – 12; 48 ÷ 12 = 4 Third option: 72 – 24; 72 ÷ 24 = 3 Fourth option: 44 – 11; 44 ÷ 11 = 4
So, the third option is different from the other options as the quotient after division is 4 in all the options except the third one. Hence, the third option is correct.
Question : Study the graph and answer the question.
What percentage of the total number of workers in the factory is the number of workers whose weekly earnings are INR 6,500 or above but less than INR 8,500? (Your answer should be correct to one decimal place.)
Option 1: 50.2
Option 2: 42.6
Option 3: 35.8
Option 4: 49.3
Correct Answer: 49.3
Solution : The total number of workers in the factory are = 60 + 85 + 95 + 105 + 90 + 80 + 70 + 65 + 50 = 700 Number of workers whose weekly earnings are INR 6500 or above but less than INR 8,500 = 105 + 90 + 80 + 70 = 345 Required percentage = $\frac{345}{700} \times 100$ = 49.3% Hence, the correct answer is 49.3.
Question : Directions: In the following question, select the number that can be placed at the sign of the question mark (?) from the given alternatives.
Option 1: 72
Option 2: 76
Option 3: 80
Option 4: 84
Correct Answer: 80
Solution : In the row, add the square of the first and the third number and the add second number to the resultant number to obtain the fourth number.
In the first row: 32 + 52 = 9 + 25 = 34 and 34 + 11 = 45 In the second row: 22 + 62 = 4 + 36 = 40 and 40 + 4 = 44 Similarly, in the third row: 32 + 82 = 9 + 64 = 73 and 73 + 7 = 80
So, 80 is the missing number in the given figure. Hence, the third option is correct.
Question : A person crosses a 900-metre-long street in 6 minutes. The speed of the person, in km/hr, is:
Option 1: 10
Option 2: 9
Option 3: 5
Option 4: 8
Correct Answer: 9
Solution : Given, Length of the street = 900 m = 0.9 km Time = 6 min = $\frac{6}{60}$ hours = $\frac{1}{10}$ hours We know, Speed = $\frac{\text{Distance}}{\text{Time}}$ = $\frac{0.9}{\frac{1}{10}}$ km/hr = 9 km/hr Hence, the correct answer is 9.
