Question : Study the below pie chart and answer the question the following question: If the pie chart shows the distribution of 36 marbles among 3 persons, then the number of marbles Madhuri has is:
Option 1: 12
Option 2: 8
Option 3: 16
Option 4: 18
Correct Answer: 18
Solution : Given: The pie chart shows the distribution of 36 marbles among 3 persons. In 360°, 36 marbles are distributed. So, in 1°, number of marbles = $\frac{36}{360°}$. Then, the number of marbles Madhuri has is $\frac{36}{360°}$ × 180° = 18 marbles Hence, the correct answer

Question : Directions: Rita travelled 35 km from a point towards the south and then turned left and travelled 20 km and finally turned left again and travelled 35 km. In which direction is she from the starting point?
Option 1: East
Option 2: West
Option 3: North
Option 4: South

Option 1: H2O+ heat
Option 2: CO2 + H2O + heat and light
Option 3: CO2 + H2O
Option 4: CO2 + heat and light
Correct Answer: CO2 + H2O + heat and light
Solution : The correct option is CO2 + H2O + heat and light.
When Ethanol (CH3CH2OH) reacts with oxygen (O2) in the presence of a suitable catalyst, combustion
Question : An arc on a circle, whose length is 19.25 cm, subtends an 18° angle at the centre. What is the area of the circle? [Use $\pi = \frac{22}{7}$]
Option 1: 11796.625 cm2
Option 2: 11786.625 cm2
Option 3: 11780.625 cm2
Option 4: 11790.625 cm2
Correct Answer: 11790.625 cm2
Solution : Here, $2 × \pi × r × \frac{\theta }{360°} = 19.25$ Where $r$ is the radius and $\theta$ is the central angle of the arc. ⇒ $2 × \frac{22}{7} × r × \frac{18 }{360} = 19.25$ ⇒ $r = \frac{35 × 7}{4} =
Question : From 40 metres away from the foot of a tower, the angle of elevation of the top of the tower is 60°. What is the height of the tower?
Option 1: $\frac{120}{\sqrt{3}}$ m
Option 2: $\frac{60}{{\sqrt3}}$ m
Option 3: $\frac{50}{{\sqrt3}}$ m
Option 4: $\frac{130}{{\sqrt7}}$ m
Correct Answer: $\frac{120}{\sqrt{3}}$ m
Solution : Let height of the tower = $h$ m From the figure, $\tan 60°=\frac{h}{40}$ ⇒ $\sqrt{3}=\frac{h}{40}$ ⇒ $h=40\sqrt{3}$ m Rationalising we get, ⇒ $ h =40\sqrt{3} \times \frac{\sqrt{3}}{\sqrt{3}} = \frac{120}{\sqrt{3}}$ m Hence, the correct answer is $\frac{120}{\sqrt{3}}$ m.

Question : An amount becomes double in 8 years on simple interest. In how many years would Rs. 25,000 become Rs. 1,00,000 with the same rate of interest?
Option 1: 32
Option 2: 28
Option 4: 24
Correct Answer: 24
Solution : Let the principal sum be P and the rate be R. Simple Interest, SI = P Time, n = 8 years Simple Interest =$\frac{\text{Principal×Rate×Time}}{100}$ ⇒ P = $\frac{P×R×8}{100}$ ⇒ R = $\frac{100}{8}$ = 12.5% ⇒ P = Rs. 25,000 Total amount = P + Simple
Question : Directions: In the following question, out of the four alternatives, select the alternative that will improve the bracketed part of the sentence. In case no improvement is needed, select "No Improvement".
