Question : Directions: In the following question, some parts of the sentence have errors, and some are correct. Find out which part of the sentence has an error. The number of that part is the answer. If a sentence is error-free, your answer is "No Error."
In that wholesale shop (1) / they do not sell (2) / fewer than ten bags of rice. (3) / No Error (4)
Option 1: (1)
Option 2: (2)
Option 3: (3)
Option 4: (4)
Correct Answer: (4)
Solution : The correct choice is the fourth option.
There is no error in the sentence as "fewer" is used for countable nouns. Though rice is an uncountable noun, "fewer" should be used in this case as bags of rice are countable.
Therefore, the sentence is "In

Question : The average of 8 numbers is 18. If one of the numbers is excluded, the average becomes 20. Find the excluded number.
Option 1: 6
Option 2: 10
Option 3: 8
Option 4: 4
Correct Answer: 4
Solution : An average of 8 numbers = 18 So, the sum of the 8 numbers = 8 × 18 = 144 If one number is excluded, then the sum of the 7 numbers = 7 × 20 = 140 Excluded number = 144 – 140 =
Question : An aeroplane flying horizontally at a height of 3 km above the ground is observed at a certain point on earth to subtend an angle of $60^\circ$. After 15 seconds of flight, its angle of elevation is changed to $30^\circ$. The speed of the aeroplane (Take $\sqrt{3}=1.732$) is:
Option 1: 230.63 m/s
Option 2: 230.93 m/s
Option 3: 235.85 m/s
Option 4: 236.25 m/s
Correct Answer: 230.93 m/s
Solution : AB = CD = 3 km = 3000 m In $\triangle$AOB, $\tan60^{\circ}=\frac{AB}{OB}$ ⇒ $OB=\frac{3000}{\sqrt3}=1000\sqrt3$ m In $\triangle$COD, $\tan30^{\circ}=\frac{CD}{OC}$ ⇒ $OC=3000\sqrt3$ m So, BC = AD = ($3000\sqrt3–1000\sqrt3)=2000\sqrt3$ m Therefore, the speed of the aeroplane = $\frac{2000\sqrt3}{15}$ m/s = 230.93 m/s Hence, the correct answer
Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the given 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.) (15, 45, 90) (8, 24, 48)
Option 1: (9, 27, 45)
Option 2: (7, 21, 24)
Option 3: (6, 18, 36)
Option 4: (12, 36, 68)
Correct Answer: (6, 18, 36)
Solution : Given: (15, 45, 90); (8, 24, 48)
Like, (15, 45, 90)→15 × 3 = 45 and 15 × 6 = 90 (8, 24, 48)→8 × 3 = 24 and 8 × 6 = 48

Question : What will be the value of $\frac{\sin 30^{\circ} \sin 40^{\circ} \sin 50^{\circ} \sin 60^{\circ}}{\cos 30^{\circ} \cos 40^{\circ} \cos 50^{\circ} \cos 60^{\circ}}$?
Option 1: $\frac{1}{\sqrt{2}}$
Option 2: $\sqrt{3}$
Option 3: $1$
Option 4: $\frac{1}{\sqrt{3}}$
Correct Answer: $1$
Solution : Given: $\frac{\sin 30^{\circ} \sin 40^{\circ} \sin 50^{\circ} \sin 60^{\circ}}{\cos 30^{\circ} \cos 40^{\circ} \cos 50^{\circ} \cos 60^{\circ}}$ = $\frac{\sin (90^{\circ}-60^{\circ}) \sin (90^{\circ}-50^{\circ}) \sin (90^{\circ}-40^{\circ}) \sin (90^{\circ}-30^{\circ})}{\cos 30^{\circ} \cos 40^{\circ} \cos 50^{\circ} \cos 60^{\circ}}$ = $\frac{\cos 60^{\circ} \cos 50^{\circ} \cos 40^{\circ} \cos 30^{\circ}}{\cos 30^{\circ} \cos 40^{\circ} \cos
Question : A is twice as fast as B and B is thrice as fast as C. The journey covered by C in $1\frac{1}{2}$ hour will be covered by A in:
Option 1: 15 minutes
Option 2: 30 minutes
Option 3: 1 hour
Option 4: 10 minutes
Correct Answer: 15 minutes
Solution : Given: A is twice as fast as B and B is thrice as fast as C. The journey is covered by C in $1\frac{1}{2}$ hour. Let the speed of C be $x$ metre/min. So, the speed of B will be $3x$ metre/min. And the
