Question : Simplify the following expression.
120 ÷ 15 of 4 + [11 × 4 ÷ 4 of {4 × 2 – (8 – 11)}]

Option 1: $\frac{120}{61}$

Option 2: $\frac{61}{120}$

Option 3: $3$

Option 4: $-3$

Team Careers360 26th Jan, 2024

Correct Answer: $3$


Solution : 120 ÷ 15 of 4 + [11 × 4 ÷ 4 of {4 × 2 – (8 – 11)}]
= 120 ÷ 15 of 4 + [11 × 4 ÷ 4 of {4 × 2 + 3}]
= 120 ÷ 15 of 4 + [11

Question : The sum of the three numbers is 540. The ratio of second to third is 9 : 13 and that of first to third is 2 : 7. The third number is:

Option 1: 273

Option 2: 280

Option 3: 250

Option 4: 286

Team Careers360 27th Jan, 2024

Correct Answer: 273


Solution : The ratio of 2nd : 3rd = 9 : 13
And the ratio of 1st : 3rd = 2:7
3rd number is common in both ratios, so to make the value equal, we need to multiply by 7 in 9 : 13 and by 13

Question : The angle of elevation of the top of a tower, vertically erected in the middle of a paddy field, from two points on a horizontal line through the foot of the tower are given to be $\alpha$ and $\beta(\alpha>\beta)$. The height of the tower is $h$ units. A possible distance (in the same unit) between the points is:

Option 1: $\frac{h(\cot\beta–\cot\alpha)}{\cos(\alpha+\beta)}$

Option 2: $h(\cot\alpha–\cot\beta)$

Option 3: $\frac{h(\tan\beta–\tan\alpha)}{\tan\alpha\tan\beta}$

Option 4: $h(\cot\alpha+\cot\beta)$

Team Careers360 27th Jan, 2024

Correct Answer: $h(\cot\alpha+\cot\beta)$


Solution :
$AD=h$ unit
In $\Delta ADB$,
$\tan\alpha=\frac{AD}{BD}$
$⇒\tan\alpha=\frac{h}{BD}$
$⇒BD=h\cot\alpha$ --------------------------------------(1)
In $\Delta ADC$,
$\tan\beta=\frac{AD}{DC}$
$⇒\tan\beta=\frac{h}{DC}$
$⇒DC=h\cot\beta$ -------------------------------------(2)
Now $BC=BD+DC$
$⇒BC=h\cot\alpha+h\cot\beta$
$\therefore BC=h(\cot\alpha+\cot\beta)$
Hence, the correct answer is $h(\cot\alpha+\cot\beta)$.

Question : Which of the following is correct?

Option 1: $\frac{2}{3}< \frac{3}{5}< \frac{11}{15}$

Option 2: $\frac{3}{5}< \frac{2}{3}< \frac{11}{15}$

Option 3: $\frac{11}{15}< \frac{3}{5}< \frac{2}{3}$

Option 4: $\frac{3}{5}< \frac{11}{15}< \frac{2}{3}$

Team Careers360 27th Jan, 2024

Correct Answer: $\frac{3}{5}< \frac{2}{3}< \frac{11}{15}$


Solution : Given: The numbers are $\frac{2}{3}, \frac{3}{5}, \frac{11}{15}$.
To find the greatest fraction, we have to find the LCM of denominators.
LCM of denominators $=$ LCM $(3, 5, 15) = {(3×5)} = 15$
We have to make all denominators the same for comparison,
