Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the following sets. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. Example 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.)
(23, 6, 35) 
(13, 5, 23)

Option 1: (24, 5, 33)

Option 2: (16, 4, 20)

Option 3: (25, 8, 41)

Option 4: (13, 7, 28)

Team Careers360 25th Jan, 2024

Correct Answer: (25, 8, 41)


Solution : Given:
(23, 6, 35) (13, 5, 23)

In the given set of numbers, multiply 2 by the second number and then add the first number to get the third number.
(23, 6, 35)→6 × 2 = 12 + 23 = 35
(13, 5, 23)→5 × 2 = 10 + 13 = 23
Let's check each option –
First option: (24, 5, 33)→5 × 2 = 10; 10 + 24 = 34 ≠ 33
Second option: (16, 4, 20)→4 × 2 = 8; 8 + 16 = 24 ≠ 20
Third option: (25, 8, 41)→8 × 2 = 16; 16 + 25 = 41
Fourth option: (13, 7, 28)→7 × 2 = 14; 14 + 13 = 27 ≠ 28

So, (25, 8, 41) follows the same pattern. Hence, the third option is correct.

Question : If $k\left(\tan 45^{\circ} \sin 60^{\circ}\right)=\cos 60^{\circ} \cot 30^{\circ}$, then the value of k is:

Option 1: $1$

Option 2: $2$

Option 3: $\frac{1}{\sqrt{3}}$

Option 4: $\sqrt{3}$

Team Careers360 25th Jan, 2024

Correct Answer: $1$


Solution : The given equation is $k\left(\tan 45^{\circ} \sin 60^{\circ}\right)=\cos 60^{\circ} \cot 30^{\circ}$.
$⇒k\left(1 \times \frac{\sqrt{3}}{2}\right) = \frac{1}{2} \times \sqrt{3}$
$⇒k = \frac{\frac{1}{2} \times \sqrt{3}}{\frac{\sqrt{3}}{2}} = \frac{1}{2} \times \frac{2}{\sqrt{3}} \times \sqrt{3} = 1$
Hence, the correct answer is $1$.

Question : A man has to be at a certain place at a certain time. He finds that he shall be 20 minutes late if he walks at 3 km/hr speed and 10 minutes earlier if he walks at a speed of 4 km/hr. The distance he has to walk is:

Option 1: 24 km

Option 2: 12.5 km

Option 3: 10 km

Option 4: 6 km

Team Careers360 25th Jan, 2024

Correct Answer: 6 km


Solution : Let $x$ be the required distance.
Time taken in the first case = $\frac{x}{3}$ hours
Time taken in the second case = $\frac{x}{4}$ hours
Time difference = $\frac{x}{3} - \frac{x}{4}$ hours
So, $\frac{x}{3} - \frac{x}{4}$ = $\frac{(20+10)}{60}$
⇒ $\frac{x}{12}$ = $\frac{1}{2}$
⇒ $x$ = 6 km
Hence, the correct answer is 6 km.
