Therefore, the correct sentence is "Christina's friends preferred her remedies
Question : From the top of a 20 metres high building, the angle of elevation from the top of a tower is 60° and the angle of depression of its foot is at 45°, then the height of the tower is: $(\sqrt{3} = 1.732)$
Option 1: 45.46 metres
Option 2: 45.64 metres
Option 3: 54.64 metres
Option 4: 54.46 metres
Correct Answer: 54.64 metres
Solution : In $\triangle BDE$, $\tan 45°=\frac{BD}{DE}$ ⇒ $1=\frac{20}{DE}$ ⇒ $DE=20$ metres ⇒ $DE=BC=20$ metres In $\triangle ABC$, $\tan 60°=\frac{AC}{BC}$ ⇒ $\sqrt{3}=\frac{AC}{20}$ ⇒ $AC=20\sqrt{3}=20\times1.732=34.64$ metres So, the height of the tower is (34.64 + 20) = 54.64 metres Hence, the correct answer is 54.64 metres.

Question : Find the value of the given expression: $10 \div 5 × 1+3 - [8 - \{5 - (7 - 7 - 9)\}]$
Option 1: 11
Option 2: 10
Option 3: 9
Option 4: 8
Correct Answer: 11
Solution : Given: 10 ÷ 5 × 1 + 3 – [8 – {5 – (7 – 7 – 9)}] Using the BODMAS rule, we get, = 10 ÷ 5 × 1 + 3 – [8 – {5 – ( –9)}] = 10 ÷ 5 × 1
Question : Directions: Select the figure that will replace the question mark (?) in the following figure series.
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : According to the given figure series, in every alternate box, the geometrical figures/ letters/ numbers at certain positions shift their position following the below pattern – 1. Box 1 to box 2 and box 3 to box 4 follow the same pattern. 2. Box 2 to
Question : The compound in which a hydroxy group, -OH, is attached to a saturated carbon atom which has two other carbon atoms attached to it is called:
Option 1: aldehyde
Option 2: tertiary alcohol
Option 3: secondary alcohol
Option 4: primary alcohol
Correct Answer: secondary alcohol
Solution : The correct option is secondary alcohol.
The compound in which a hydroxy group, -OH, is attached to a saturated carbon atom which has two other carbon atoms attached to it is called secondary alcohol. In secondary alcohols, the carbon atom bearing the hydroxy group
Question : The expression $\frac{\tan57°+\cot37°}{\tan33°+\cot53°}$ is equal to:
Option 1: $\tan33°\cot57°$
Option 2: $\tan57°\cot37°$
Option 3: $\tan33°\cot53°$
Option 4: $\tan53°\cot37°$
Correct Answer: $\tan57°\cot37°$
Solution : Given: $\frac{\tan57°+\cot37°}{\tan33°+\cot53°}$ = $\frac{\tan57°+\cot37°}{\tan(90°-57°)+\cot(90°-37°)}$ = $\frac{\tan57°+\cot37°}{\cot57°+\tan37°}$ = $\frac{\tan57°+\cot37°}{\frac{1}{\tan57°}+\frac{1}{\cot37°}}$ = $\tan57°\cot37°[\frac{\tan57°+\cot37°}{\tan57°+\cot37°}]$ = $\tan57°\cot37°$ Hence, the correct answer is $\tan57°\cot37°$.
