Question :
Which one is not a function of money?
Option 1:
Transfer of value
Option 2:
Store of value
Option 3: Price stabilisation
Option 4: Value measurement
Correct Answer: Price stabilisation
Solution : The correct answer is Price stabilisation.
Price stability does not fall under the purview of a specific monetary function. It entails the continuous maintenance of consistent prices over time, a goal that can be accomplished through the implementation of either monetary or
Question : The value of $\sqrt {10 ^{-6} \times 0.25 }$.
Option 1: 0.0025
Option 2: 0.0005
Option 3: 0.25
Option 4: 0.50
Correct Answer: 0.0005
Solution : $\sqrt {10 ^{-6} \times 0.25 }$ $=10^-3\times 0.5$ $=0.0005$ Hence, the correct answer is 0.0005.
Question : If $\sin A=\frac{2}{3}$, then find the value of (7 – tan A)(3 + cos A).
Option 1: $\frac{61}{3}+\frac{17}{3 \sqrt{5}}$
Option 2: $\frac{61}{3 \sqrt{5}}+\frac{17}{3}$
Option 3: $\frac{61}{3}+\frac{17}{\sqrt{5}}$
Option 4: $\frac{61}{3}-\frac{17}{3 \sqrt{5}}$
Correct Answer: $\frac{61}{3}+\frac{17}{3 \sqrt{5}}$
Solution : Given: $\sin A =\frac{2}{3}$ We know that $\sin A=\frac{\text{Perpendicular}}{\text{Hypotenuse}}=\frac{2}{3}$ We know, Hypotenuse2 = Base2 + Perpendicular2 ⇒ Base = $\sqrt{3^2-2^2}=\sqrt5$ We know, $\cos A =\frac{\text{Base}}{\text{Hypotenuse}}=\frac{\sqrt{5}}{3}$ And, ⇒ $\tan A=\frac{\sin A}{\cos A}=\ \frac{2}{\sqrt{5}}$ Now, $\left ( 7-\tan A \right )\left ( 3+\cos
Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the following 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.) (6, 2, 96); (5, 6, 240)
Option 1: (4, 1, 6)
Option 2: (12, 3, 45)
Option 3: (1, 2, 16)
Option 4: (8, 3, 28)
Correct Answer: (1, 2, 16)
Solution : Given: (6, 2, 96); (5, 6, 240)
Like, (6, 2, 96)→(6 × 2) × 8 = 96 (5, 6, 240)→(5 × 6) × 8 = 240 Let's check the options – First option: (4, 1, 6)→(4 × 1) × 8 = 32 ≠
Question : Directions: Pratima departs from her house and walks 29 m towards the north, then turns right and walks 16 m. Now she turns right again and walks 17 m. She again, takes a right turn and stops after walking for 21 m. What is the shortest distance between Pratima and her house now? (Assuming that all turns are 90-degree turns only.)
Option 1: 17 m
Option 2: 18 m
Option 3: 13 m
Option 4: 12 m
Correct Answer: 13 m
Solution : First, we will draw the diagram, as per the given instructions –
Here, A is the starting point and F is the finishing point. AB = 29 m; BC = DE = 16 m; CD = BE = 17 m; DF = 21 m
Question : Directions: Select the option that represents the letters that when placed from left to right in the blanks below will complete the letter series. AA_D_F_AC_E_A_ _D_F_ACD_F
Option 1: CAFDFAACEE
Option 2: CEADFACEAE
Option 3: ACDAFACEAE
Option 4: CEAFDACEAC
Correct Answer: CEADFACEAE
Solution : Given: AA_D_F_AC_E_A_ _D_F_ACD_F
To fill the series we have to divide the series – AA_D_F / _AC_E_ / A_ _D_F / _ACD_F
Let's check each option – First option: CAFDFAACEE; AACDAF / FACDEF / AA A
Question : AB is a chord in a circle of radius 13 cm. From centre O, a perpendicular is drawn through AB intersecting AB at point C. The length of OC is 5 cm. What is the length of AB?
Option 1: 24 cm
Option 2: 12 cm
Option 3: 20 cm
Option 4: 15 cm
Correct Answer: 24 cm
Solution : As shown in the given figure, Perpendicular drawn from the centre of a circle to the chord bisects the chord. Therefore, AC = BC and $\angle$OCB = 90° Thus, $\triangle$OCB is a right-angled triangle. By Pythagoras Theorem, $OB^2 = OC^2 + CB^2$ $⇒CB^2 =
Question : In a Presidential Government, the President is
Option 1: independent of the Legislature
Option 2: dependent on the Legislature
Option 3: dependent on the Judiciary
Option 4: bound by the advice of the Council of Ministers
Correct Answer: independent of the Legislature
Solution : The correct option is independent of the legislature.
The President of presidential governance is elected by the people in a separate election from the legislature. Regardless of parliamentary backing, the President has a term of four to five years. This separation
Question : Directions: In a code language, OBESITY is written as EBOHYTI. How will FIXTURE be written in that language?
Option 1: XIFGERU
Option 2: XIFMERU
Option 3: XIFGEUS
Option 4: IFYGERU
Correct Answer: XIFGERU
Solution : Given: OBESITY is written as EBOHYTI.
Change the position of the first and last three letters and write the opposite letter of the middle letter of OBESITY, to obtain the required code –
Thus, OBESITY is coded as EBOHYTI. Similarly, follow the same pattern for
