Option 1: OLPA
Option 2: KLMA
Option 3: LLMA
Option 4: KLLA
Correct Answer: KLLA
Solution : Given: ELFA, GLHA, ILJA, ?, MLNA
In the given series, add 2 to the place value of the first and third letters of each term and the second and fourth letters remain constant – ELFA→E + 2 = G; L; F + 2 = H;
Question : Directions: In the following question, the given sentence has four parts marked P, Q, R, and S. Choose the part of the sentence with the error and select it as your answer. If there is no error, select "No Error (S)" as your answer.

Option 1: 1
Option 2: 2
Option 3: 3
Option 4: 4

Solution : The error in this sentence is in part (R) marked by the third option.
Explanation: The subject "investment" is singular, so the verb "have" should be replaced with its singular form "has". Investment is a singular subject, so the verb "has" should agree with it
Question : Directions: Select the figure that will replace the question mark (?) in the following figure series.
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : According to the given figure series – 1. The shaded arrow located at the centre of the box rotates 90° in a clockwise direction. 2. The symbols in the corner, remain in the same positions and become shaded in a clockwise direction. On the other hand,
Question : The value of $11. \overline{4}+22.5 \overline{67}-33.5 \overline{9}$ is:
Option 1: $40. \overline{12}$
Option 2: $4. \overline{12}$
Option 3: $0.4\overline{12}$
Option 4: $0.04\overline{12}$
Correct Answer: $0.4\overline{12}$
Solution : $11 . \overline{4}+22.5 \overline{67}-33.5 \overline{9}$ $= 11 + .\overline{4} + 22 + .5 \overline{67} - 33 - .5 \overline{9}$ $= .\overline{4} + .5 \overline{67} - .5 \overline{9}$ $= \frac{4}{9} + \frac{567-5}{990} - \frac{59-5}{90}$ $= \frac{440}{990} + \frac{562}{990} - \frac{594}{990}$ $= \frac{440 + 562 - 594}{990}$
Question : Two circles touch each other externally. The radius of the first circle with centre O is 12 cm. Radius of the second circle with centre A is 8 cm. Find the length of their common tangent BC.
Option 1: $6 \sqrt{6} \mathrm{~cm}$
Option 2: $8 \sqrt{3} \mathrm{~cm}$
Option 3: $8 \sqrt{2} \mathrm{~cm}$
Option 4: $8 \sqrt{6} \mathrm{~cm}$
Correct Answer: $8 \sqrt{6} \mathrm{~cm}$
Solution : Given: $r{_1}=12, r{_2}=8$ Length of the direct common tangent $=\sqrt{d^2-(r{_1} -r{_2})^2}$ where $d=r{_1}+r{_2}$ $=\sqrt{(12+8)^2-(12-8)^2}$ $=\sqrt{20^2 - 4^2} = \sqrt{400-16}=\sqrt{384}=8\sqrt6$ cm Hence, the correct answer is $8 \sqrt{6} \mathrm{~cm}$.
Question : Which one of the following Indian World Heritage Sites is not in Madhya Pradesh ?
Option 1: Khajuraho Temples

Question : Directions: In a certain code language, APPRECIATE is written as ETAICERPPA, and MOTIVATION is written as NOITAVITOM. How will FRIENDSHIP be written in that language?
Option 1: PIHSDNIERF
Option 2: PIHSDENIRF
Option 3: PIHSNDEIRF
Option 4: PIHSDNEIRF
Correct Answer: PIHSDNEIRF
Solution : Given: APPRECIATE is written as ETAICERPPA MOTIVATION is written as NOITAVITOM
Revere the letters of the words – APPRECIATE→ETAICERPPA Thus, APPRECIATE is coded as ETAICERPPA. MOTIVATION→NOITAVITOM Thus, MOTIVATION is coded as NOITAVITOM. Similarly, follow the same pattern for FRIENDSHIP→PIHSDNEIRF
So, FRIENDSHIP is coded as PIHSDNEIRF.
Question : Directions: Select the option figure that is embedded in the given figure as its part (rotation is NOT allowed).
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, only the fourth option figure is embedded in the given question figure.
Hence, the fourth option is correct.
Question :

Option 1: Cell membrane
Option 2: Cell wall
Option 3: Nucleolus
Option 4: Mitochondria
Correct Answer: Cell wall
