Question : Directions: Select the option that is related to the third number in the same way as the second number is related to the first number and the sixth number is related to the fifth number. 3856 : 8563 :: 4893 : ? :: 2873 : 8732
Option 1: 8934
Option 2: 3948
Option 3: 3984
Option 4: 8943
Correct Answer: 8934
Solution : Given: 3856 : 8563 :: 4893 : ? :: 2873 : 8732
In the above-given pairs, the second digit shifts to the first place followed by the third, fourth, and first digit. 3856→8563 2873→8732 Similarly, 4893→8934
So, 8934 is related to 4893. Hence, the first
Question : A boy goes from home to school at a speed of 30 km/hr and returns back at a speed of 70 km/hr. What is his average speed for the journey?
Option 1: 42 km/hr
Option 2: 48 km/hr
Option 3: 38 km/hr
Option 4: 36 km/hr
Correct Answer: 42 km/hr
Solution : Given: Going speed = 30 km/hr Returning speed = 70 km/hr We know that, $\text{Average speed} =\frac{2S_1S_2}{S_1+S_2}=\frac{2×30×70}{30+70}=42$ km/hr Hence, the correct answer is 42 km/hr.
Question : Directions: A statement is given followed by two inferences I and II. You have to consider the statement to be true even if it seems to be at variance with commonly known facts. You have to decide which of the given inferences, if any, follow from the given statement. Statement: Extensive use of pesticides in agricultural production contaminates soil and water, remains in the crops, and finally enters the food chain, thereby posing a threat to human beings. Inferences: I. Excessive use of pesticides in agricultural production is not good for people. II. Excessive use of pesticides in agricultural production can have a bad effect on water.
Option 1: If only II follows
Option 2: If neither I nor II follows
Option 3: If only I follows
Option 4: If both I and II follow
Correct Answer: If both I and II follow
Solution : Given: Statement: Extensive use of pesticides in agricultural production contaminates soil and water, remains in the crops, and finally enters the food chain, thereby posing a threat to human beings.
Inferences: I. Excessive use of pesticides in agricultural production is
Question : The value of 97 × 103 is _________.
Option 1: 7999
Option 2: 9991
Option 3: 8991
Option 4: 9981
Correct Answer: 9991
Solution : 97 × 103 = (100 - 3) × (100 + 3) = 1002 - 32 = 10000 - 9 = 9991 Hence, the correct answer is 9991.
Question : Evaluate the following: $\cos \left(36^{\circ}+A\right) \cdot \cos \left(36^{\circ}-A\right)+\cos \left(54^{\circ}+A\right) \cdot \cos \left(54^{\circ}-A\right)$
Option 1: $\sin 2A$
Option 2: $\cos A$
Option 3: $\sin A$
Option 4: $\cos 2A$
Correct Answer: $\cos 2A$
Solution : $\cos (36^{\circ}+A). \cos (36^{\circ}-A)+\cos (54^{\circ}+A) .\cos (54^{\circ}-A)$ = $\cos (36^{\circ}+A) . \cos (36^{\circ}-A)+\sin [90^{\circ}-(54^{\circ}+A)] . \sin [90^{\circ}-(54^{\circ}-A )]$ = $\cos (36^{\circ}+A) \cdot \cos (36^{\circ}-A)+\sin (36^{\circ}-A) \cdot \sin (36^{\circ}+A)$ = $\cos (36^{\circ}+A-36^{\circ}+A )$ [$\because \cos(A- B) =\sin A.\sin B +\cos A. \cos B$] = $\cos
Question : Directions: Select the correct mirror image of the given combination when the mirror is placed at PQ as shown below.
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : As per the mirror image properties, closer things appear closer to the mirror in the reflection. So, according to the above property and the information provided, the mirror is placed on the right side of the figure (on line PQ). So, the left side of the
