Question : In a 1 km linear race, P beats Q by 120 metres or 30 sec. What is the time taken by P to cover the race?

Option 1: 220 sec

Option 2: 250 sec

Option 3: 235 sec

Option 4: 240 sec

Team Careers360 26th Jan, 2024

Question : ABCD is a trapezium with AD and BC parallel sides and E is a point on BC. The ratio of the area of ABCD to that of AED is:

Option 1: $\mathrm{\frac{AD}{BC}}$

Option 2: $\mathrm{\frac{BE}{EC}}$

Option 3: $\mathrm{\frac{AD+BE}{AD+CE}}$

Option 4: $\mathrm{\frac{AD+BC}{AD }}$

Team Careers360 27th Jan, 2024

Correct Answer: $\mathrm{\frac{AD+BC}{AD }}$


Solution :

The area of a trapezium,
$\text{Area} = \frac{1}{2} \times (\text{sum of parallel sides}) \times \text{height}$
$\text{Area}_{ABCD} = \mathrm{\frac{1}{2} \times (AD + BC) \times EF}$
The area of triangle AED,
$\text{Area}_{AED} = \mathrm{\frac{1}{2} \times AD \times EF}$
The ratio of the area of ABCD to

Question : Rubi goes to a multiplex at a speed of 3 km/h to see a movie and reaches 5 minutes late. If she travels at the speed of 4 km/h she reaches 5 minutes early, then the distance of the multiplex from her starting point is:

Option 1: 2 km

Option 2: 5 km

Option 3: 2 metres

Option 4: 5 metres

Team Careers360 27th Jan, 2024

Correct Answer: 2 km


Solution : Let the distance be $x$ km.
According to the question,
Speed = $\frac{\text{Distance}}{\text {Time}}$ 
$\frac{x}{3}–\frac{x}{4}=\frac{5+5}{60}$
⇒ $x=2$
Hence, the correct answer is 2 km.

Question : The bar graph given below shows the percentage distribution of the total production of six different types of cars by a car manufacturing company over 2 years.


If 75% of the T-type cars produced each year were sold by the company, how many T-type cars remain unsold?

Option 1: 23500

Option 2: 22000

Option 3: 24125

Option 4: 25000

Team Careers360 26th Jan, 2024

Correct Answer: 24125


Solution : According to the question, 75% of the T-type cars are sold.
Now, if 75% of the T-type cars produced each year were sold by the company, the number of T-type cars remain unsold
= 350000 $\times$ (90 – 75)% $\times$ (100 – 75)% $+$ 440000
