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 : 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).
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, only the fourth option figure is embedded in the given question figure.
Hence, the fourth option is correct.

Question : Which of the following is found in plant cells only?
Option 1: Cell membrane
Option 2: Cell wall
Option 3: Nucleolus
Option 4: Mitochondria
Correct Answer: Cell wall
