Question : From an aeroplane just over of river, the angle of depression of two palm trees on the opposite bank of the river is found to be $60^{\circ}$ and $30^{\circ}$, respectively. If the breadth of the river is 400 metres, then the height of the aeroplane above the river at that instant is: $(\sqrt{3} = 1.732)$
Option 1: 173.2 metres
Option 2: 346.4 metres
Option 3: 519 .6 metres
Option 4: 692.8 metres
Correct Answer: 173.2 metres
Solution : Let, $BC$ = River = $400$ m $AD$ = Height of plane = $H$ m $BD=x$ m $CD=(400-x)$ m From $\Delta ABD$, $\tan 60^{\circ} = \frac{AD}{BD}$ $⇒\sqrt3 = \frac{H}{x}$ $⇒H = \sqrt3x$ $⇒x=\frac{H}{\sqrt3}$--------------(i) From $\Delta ADC$, $\tan 30^{\circ} = \frac{AD}{CD}$ $⇒\frac{1}{\sqrt3} = \frac{H}{400-x}$ $⇒\sqrt3H

The difference between the total number of erasers sold by P and Q is 0.
Option 1: Only II
Option 2: Both I and II
Option 3: Only I
Option 4: Neither I nor II
Correct Answer: Only I
Solution : I. The ratio of the total number of erasers sold by P in J and K to the total number of erasers sold by Q in M and N is 93 ∶ 98. Total number of erasers sold by P in J and K
Question : Kapil initiated a business with an investment of INR 30,00,000 in April 2022. After six months, his friend Kunal joined him with an investment of INR 25,00,000. In February 2023, Kapil's ex-class fellow Saloni also invested an amount equal to the total investment made by the earlier two partners. In what ratio the profit earned after 3 years from the date on which Kapil initiated the business, will be distributed?
Option 1: 332 : 200 : 50
Option 2: 108 : 75 : 143
Option 3: 432 : 300 : 55
Option 4: 432 : 400 : 55
Correct Answer: 108 : 75 : 143
Solution : Investment made by Kapil = INR 30,00,000 Time of investment made by Kapil = 36 months The investment made by Kunal = INR 25,00,000 Time of investment made by Kunal = 30 months The investment made by Saloni = INR 55,00,000
Question : The pie chart represents the modes of transport used by different employees in a university. The central angle of the sector for officers using two-wheelers is:
Option 1: 72$^{\circ}$
Option 2: 46$^{\circ}$
Option 3: 36$^{\circ}$
Option 4: 54$^{\circ}$
Correct Answer: 54$^{\circ}$
Solution : Using information from the table: Two wheeler = 15% According to the question, Central angle corresponding to two wheeler = $\frac{15}{100}×360^{\circ}$ = 54$^{\circ}$ Hence, the correct answer is 54$^{\circ}$.
Question : Directions: In the following number pairs, the second number is obtained by applying certain mathematical operations to the first number. Select the set in which the numbers are related in the same way as the numbers of the following sets. (63, 496); (42, 328) (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.)
Option 1: (48, 376)
Option 2: (25, 194)
Option 3: (37, 302)
Option 4: (63, 512)
Correct Answer: (48, 376)
Solution : Given: (63, 496); (42, 328)
In the given pairs, multiply the first number by 8 and then subtract 8 from the resulting number to obtain the second number. (63, 496)→(63 × 8) – 8 = 504 – 8 = 496 (42, 328)→(42 × 8)

Question : Two trains, each of length 125 metres, are running in parallel tracks in opposite directions. One train is running at a speed of 65 km/hr and they cross each other in 6 seconds. The speed of the other train is:
Option 1: 75 km/hr
Option 2: 85 km/hr
Option 3: 95 km/hr
Option 4: 105 km/hr
Correct Answer: 85 km/hr
Solution : Given: The first train is running at a speed of 65 km/hr. Let the speed of the second train = $x$ km/hr So, time= $\frac{\text{Length of Train 1+ Length of Train 2}}{\text{Relative speed in opposite direction}}$ $⇒6=\frac{125+125}{(65+x)×\frac{5}{18}}$ $⇒65+x=50×3$ $⇒x= 150 - 65$ $\therefore x=
