Question : Directions: Select the odd group of numbers. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g.13 – Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
Option 1: (18 – 28 – 48 )
Option 2: (17 – 27 – 47 )
Option 3: (15 – 25 – 49 )
Option 4: (13 – 23 – 43 )
Correct Answer: (15 – 25 – 49 )
Solution : Let's check each option – First option: (18 – 28 – 48 ); 18 + 10 = 28; 28 + 20 = 48 Second option: (17 – 27 – 47 ); 17 + 10 = 27; 24 + 20 =
Question : The given chart shows the marks scored by a class X student in different subjects (Values are in Degrees).
If the total marks are 1800, find the marks in social science.
Option 1: 350
Option 2: 306
Option 3: 360
Option 4: 72
Correct Answer: 360
Solution : Given: The marks scored by Class X in different subjects (Values are in Degrees) is (60° + 62° + 72°+ 84° + 82°) = 360° Total marks across subjects is 1800. So, 1° $=$ $\frac{1800}{360°}=5$ marks Hence, the marks in Social Science are 5 ×
Question : Directions: Two positions of a cube are shown below. What will come opposite to face containing 4?
Option 1: 1
Option 2: 2
Option 3: 3
Option 4: 6
Correct Answer: 1
Solution : According to the given positions of the cube, the common face is 5. Moving clockwise from common face 5, the following opposite pairs of faces will be formed – (Assume that the sixth face of the dice is 3.)
Based on the diagram, the face
Question : In the triangle $\mathrm{ABC}, \mathrm{AB}=12 \mathrm{~cm},\mathrm{AC}=10 \mathrm{~cm}$, and $\angle \mathrm{BAC}=60^{\circ}$. What is the value of the length of the side $\mathrm{BC}$?
Option 1: 10 cm
Option 2: 7.13 cm
Option 3: 13.20 cm
Option 4: 11.13 cm
Correct Answer: 11.13 cm
Solution : Given, $\mathrm{AB}=12 \mathrm{~cm},\mathrm{AC}=10 \mathrm{~cm}$, and $\angle \mathrm{BAC}=60^{\circ}$ According to cosine law, $\mathrm{BC}^2=\mathrm{AB}^2+\mathrm{AC}^2-2(\mathrm{AB})(\mathrm{AC})\cos 60^\circ$ ⇒ $\mathrm{BC}^2=12^2+10^2-2\times12\times10\times0.5$ $\therefore \mathrm{BC}=11.13\mathrm{~cm}$ Hence, the correct answer is 11.13 cm.
Question : What is the diameter (in cm) of a sphere with a surface area of 6.16 sq. cm?
Option 1: 1.4
Option 2: 0.7
Option 3: 2.8
Option 4: 2.1
Correct Answer: 1.4
Solution : Let the radius be $r$. The total surface area of a sphere = $4\pi r^2$ ⇒ $6.16=4\pi r^2$ ⇒ $6.16=4×\frac{22}{7}×r^2$ ⇒ $r^2=\frac{49}{100}$ $\therefore r=0.7$ cm Diameter = $2×r=2×0.7=1.4$ cm Hence, the correct answer is 1.4.
