Question : In a triangle $ABC$, side $BC$ is produced to $D$ such that $\angle A C D=127^{\circ}$. If $\angle A B C=35^{\circ}$, then find $\angle B A C$.

Option 1: 82°

Option 2: 92°

Option 3: 95°

Option 4: 75°

Team Careers360 25th Jan, 2024

Correct Answer: 92°


Solution :
Given, In a triangle $ABC$, $\angle A C D=127^{\circ}$ and $\angle A B C=35^{\circ}$
By exterior angle property,
$\angle A C D = \angle A B C+\angle B A C$
$⇒127^{\circ} = 35^{\circ}+\angle B A C$
$⇒\angle B A C=127^{\circ} - 35^{\circ}$
$\therefore\angle B A

Question : The following bar graph shows the sales of tractors by a showroom in different months. What was the approximate percentage decline from August to September?

Option 1: 33%

Option 2: 51%

Option 3: 46%

Option 4: 55%

Team Careers360 25th Jan, 2024

Correct Answer: 46%


Solution : Number of tractors sold in September = 1875
Number of tractors sold in August = 3475
The decline in the number of tractors from August to September = 3475 – 1875 = 1600
Percentage decline in the number of tractors = $\frac{1600}{3475} \times 100 =

Question : If $\tan 2 \theta=\cot \left(\theta-36^{\circ}\right)$, where $2 \theta$ is an acute angle, then the value of $\theta$ is:

Option 1: 18°

Option 2: 36°

Option 3: 30°

Option 4: 42°

Team Careers360 25th Jan, 2024

Correct Answer: 42°


Solution : Given, $\tan 2 \theta=\cot \left(\theta-36^{\circ}\right)$
⇒ $\tan 2 \theta=\tan \left(90^{\circ}-\theta+36^{\circ}\right)$
⇒ $2\theta=126^{\circ}-\theta$
⇒ $3\theta=126^{\circ}$
$\therefore \theta=42^{\circ}$
Hence, the correct answer is 42°.

Question : If the sum of squares of two real numbers is 12 and the product of the numbers is 4, find the difference between the numbers.

Option 1: 4

Option 2: 8

Option 3: 1

Option 4: 2

Team Careers360 25th Jan, 2024

Correct Answer: 2


Solution : Given:
The sum of squares of two numbers = 12
Product of the numbers = 4
Let the numbers be $a$ and $b$.
⇒ $a^2+b^2=12$ and $ab = 4$
We know, $(a-b)^2=a^2+b^2-2ab$
⇒ $(a-b)^2=12-2\times4$
⇒ $(a-b)^2=12-8$
⇒ $(a-b)^2=4$
⇒ $a-b=\sqrt4=2$
Hence, the correct answer is
