Question : Directions: In a certain code language, PROFIT is coded as VIHOTP. What is the code for RACING in that code language?
Option 1: INKCCR
Option 2: INKCRC
Option 3: INKRCC
Option 4: ILNCCR
Correct Answer: INKCCR
Solution : Given: PROFIT is coded as VIHOTP.
Add 0 and 1 to the place value of each letter of PROFIT alternatively, and then reverse the order of the letters, to get the required code.
Now, reverse the letters of PTOHIV→VIHOTP So, PROFIT is coded as VIHOTP.
Question : The inradius of an equilateral triangle is $\sqrt3$ cm, then the perimeter of that triangle is:
Option 1: 18 cm
Option 2: 15 cm
Option 3: 12 cm
Option 4: 6 cm
Correct Answer: 18 cm
Solution : Given, the inradius of an equilateral triangle is $\sqrt3$ cm. We know, In-radius of equilateral triangle = $\frac{\text{side}}{2\sqrt3}$ ⇒ $\sqrt3=\frac{\text{side}}{2\sqrt3}$ ⇒ side = $\sqrt3\times2\sqrt3$ $\therefore$ side = $2\times 3$ = 6 cm Now, perimeter = 3$\times$ (side) = $3\times 6$ = 18 cm Hence,
Question : Select the INCORRECTLY spelt word.
Option 1: Calendr
Option 2: Conscientious
Option 3: Colleague
Option 4: Conspicuous

Question : The radius of a wheel is 25 cm. How many rounds it will take to complete 11 km?
Option 1: 5000
Option 2: 6000
Option 3: 7000
Option 4: 4000
Correct Answer: 7000
Solution : Distance to be completed = 11 km = 11000 m Radius, $r$ = 25 cm = 0.25 m Distance covered in one round = $2\pi r = 2 × \pi × 0.25$ m = $0.50\pi$ m $\therefore$ Number of rounds required to cover 11 km

Question : Directions: Select the option in which the numbers share the same relationship in the set as that shared by the numbers in the given set. (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.) (15, 25, 35) (45, 55, 65)
Option 1: (55, 65, 75)
Option 2: (45, 55, 70)
Option 3: (55, 75, 85)
Option 4: (55, 60, 70)
Correct Answer: (55, 65, 75)
Solution : Given: (15, 25, 35); (45, 55, 65)
Add 10 to the first and second numbers, to get the second and third numbers respectively – ⇒ (15, 25, 35)→15 + 10 = 25, 25 + 10 = 35 ⇒ (45, 55, 65)→45 + 10
Question : Water is flowing through a cylindrical canal with an internal diameter of 7 m at the speed of 18 km/hr. Find the volume of water flowing through the canal in 30 minutes. (take $\pi=\frac{22}{7}$)
Option 1: 3,76,500 m3
Option 2: 3,56,500 m3
Option 3: 3,66,500 m3
Option 4: 3,46,500 m3
Correct Answer: 3,46,500 m3
Solution : Given: Water is flowing through a cylindrical canal with an internal diameter of 7 m at the speed of 18 km/hr. The internal radius of the cylinder = $\frac{7}{2}$ m Speed of water = 18 km = 18 × $\frac{5}{18}$ = 5 m/s
Question : Directions: In the following question, some parts of the sentence may have some errors. Find out which part of the sentence has an error and select the appropriate option. If the sentence is free from error, select "No error".
The poor man (1) / poisoned him (2) / and his own children. (3) / No error (4)
Option 1: (1)
Option 2: (2)
Option 3: (3)
Option 4: (4)
Correct Answer: (2)
Solution : The error lies in the second part of the sentence.
The pronoun him in the second part of the sentence should be replaced with himself to indicate that the poor man poisoned himself.
Therefore, the correct sentence would be: The poor man poisoned himself and
